Mendeliome v1.1978 TMEM216 Zornitza Stark edited their review of gene: TMEM216: Added comment: PMID 39191256: Two rare nucleotide substitutions at the same genomic location on chromosome 11 (g.61392563 [GRCh38]), 69 base pairs upstream of the start codon of the ciliopathy gene TMEM216 (c.-69G>A, c.-69G>T [GenBank: NM_001173991.3]) found in individuals of South Asian and African ancestry, respectively.

This included 71 homozygotes and 3 mixed heterozygotes in trans with a predicted loss-of-function allele. Haplotype analysis showed single-nucleotide variants (SNVs) common across families, suggesting ancestral alleles within the two distinct ethnic populations.

Clinical phenotype analysis of 62 available individuals from 49 families indicated a similar clinical presentation with night blindness in the first decade and progressive peripheral field loss thereafter. No evident systemic ciliopathy features were noted.

Functional characterization of these variants by luciferase reporter gene assay showed reduced promotor activity.; Changed publications: 20036350, 20512146, 39191256; Changed phenotypes: Joubert syndrome 2, MIM# 608091, MONDO:0011963, Meckel syndrome 2, MIM# 603194, MONDO:0011296, Retinitis pigmentosa, MONDO:0019200, TMEM216-related

Review for gene: CFAP20 was set to GREEN
Added comment: CFAP20 is a ciliopathy candidate. Demonstrate in zebrafish that cfap20 is required for motile cilia function, and in C. elegans, CFAP-20 maintains the structural integrity of non-motile cilia inner junctions, influencing sensory-dependent signalling and development.

Human patients and zebrafish with CFAP20 mutations both exhibit retinal dystrophy (retinitis pigments). Hence, CFAP20 functions within a structural./functional hub centred on the inner junction that is shared between motile and non-motile cilia, and is distinct from other ciliopathy-associaetd domains or macromolecular complexes.

Describe 8 individuals from 4 independent families with damaging biallelic variants (homozygous or compound heterozygous) in CFAP20 that segregate with retinal dystrophy. All variants cluster to one side of the protein, with two of the residues directly contacting alpha-tubullin.

Family 1 - consanguineous set of 3 siblings from Sudan, homozygous for CFAP20 c.305G>A; p.Arg102His (they also had a homozygous variant in DYNC1LI2 however CFAP20 was considered the better candidate.
Family 2 - 3 siblings from Spain, 2 with retinal dystrophy, 1 genetically tested and has c.337C>T; p.(Arg113Trp) and c.397delC; p.(Gln133Serfs*5)
Family 3 - single affected family member compound het for c.164+1G>A and c.457A>G; p.(Arg153Gly).
Family 4 - 3 affected siblings with generalised retinopathy and variable neurological deficits with c.164+1G>A and c.257G>A; p.(Tyr86Cys)

For all families, no individuals had signs of polycystic kidney disease; however, not all individuals had kidney imaging. Visual defecit phenotype presented between adolescence and adulthood (17-56 years old).

Used HEK293T cell expression studies to demonstrate a statistically significant decline of mutated CFAP20 protein levels (with the exception of p.Arg102His). To test the specific variants, they used the C.elegans orthologues.

Added comment: 2 patients from reportedly unrelated consanguineous Moroccan families with the same homozygous frameshift variant reported with late-onset retinal degeneration. Patient 1 was diagnosed with RP at age 60, patient 2 at age 69. Both reported loss of visual acuity in the years prior.

Immunoblotting of cell lysates from patient fibroblasts showed that some mutant transcript escaped NMD. Functional testing showed that the truncated protein could bind microtubules but was unable to associate with centrioles or its interaction partner CEP290. Patient fibroblasts were shown to have delayed ciliation.

Mutant protein was unable to rescue loss of cilia in CEP162 knockdown mice supporting that the mutant protein does not retain any ciliary function, however additional data supported that the truncated protein was able to bind microtubules and function normally during neuroretinal development. The authors suggest this likely underlies the late-onset RP in both patients.

Rated Amber because only a single variant has been reported in patients who may or may not be related (same ethnic background).

Mendeliome v1.15 IKBKG Zornitza Stark edited their review of gene: IKBKG: Added comment: X-linked systemic autoinflammatory disease (SAIDX) is characterized by the onset of systemic autoinflammation in the first months of life. Features include lymphadenopathy, hepatosplenomegaly, fever, panniculitis, and nodular skin rash. Additional manifestations may include inflammation of the optic nerve, intracranial hemorrhage, and lipodystrophy. Laboratory studies show hypogammaglobulinemia, increased or decreased white blood cell count, autoimmune cytopenias, elevated serum inflammatory markers, and a type I interferon signature. 6 unrelated boys and a girl reported. All variants resulted in absence of the domain encoded by exon 5 (NEMOdelEx5).

Mendeliome v1.3 RDH11 Zornitza Stark edited their review of gene: RDH11: Added comment: 2nd case reported: 1 Chinese patient with retinitis pigmentosa, juvenile cataracts, intellectual disability, and myopathy. Trio-based WES and whole genomic CNV detection found compound heterozygous variants in RDH11 (p.Leu313Pro and c.75-3C>A) with biparental inheritance. Variant c.75-3C>A was confirmed to be a splice-site mutation by cDNA sequencing. It caused exon 2 skipping, resulting in a frameshift mutation and premature translation termination (p.Lys26Serfs*38). They found mislocalization of RDH11 protein in muscle cells of the patient by using immunofluorescence staining. Retinol dehydrogenase 11 (RDH11) is an 11-cis-retinol dehydrogenase that has a well-characterized, albeit auxiliary role in the retinoid cycle. Diseases caused by mutations in the RDH11 gene are very rare, and only one affected family with eye and intelligence involvement has been reported.; Changed rating: AMBER; Changed publications: 24916380, 15634683, 30731079, 18326732, 34988992

Added comment: 11 individuals reported, 9 that carried 8 different rare heterozygous missense variants in CLCN3, and 2 siblings that were homozygous for an NMD-predicted frameshift variant likely abolishing ClC-3 function. All missense variants were confirmed to be de novo in eight individuals for whom parental data was available.

The 11 individuals in the cohort share clinical features of variable severity. All 11 have GDD or ID and dysmorphic features, and a majority has mood or behavioural disorders and structural brain abnormalities:
- Structural brain abnormalities on MRI (9/11) included partial or full agenesis of the corpus callosum (6/9), disorganized cerebellar folia (4/9), delayed myelination (3/9), decreased white matter volume (3/9), pons hypoplasia (3/9), and dysmorphic dentate nuclei (3/9). Six of those with brain abnormalities also presented with seizures.
- Nine have abnormal vision, including strabismus in four and inability to fix or follow in the two with homozygous loss-of-function variants.
- Hypotonia ranging from mild to severe was reported in 7 of the 11 individuals.
- Six have mood or behavioural disorders, particularly anxiety (3/6).
- Consistent dysmorphic facial features included microcephaly, prominent forehead, hypertelorism, down-slanting palpebral fissures, full cheeks, and micrognathia.

The severity of disease in the two siblings with homozygous disruption of ClC-3 is consistent with the drastic phenotype seen in Clcn3 KO mice. The disease was more severe in two siblings carrying homozygous loss-of-function variants with the presence of GDD, absent speech, seizures, and salt and pepper fundal pigmentation in both individuals, with one deceased at 14 months of age. The siblings also had significant neuroanatomical findings including diffusely decreased white matter volume, thin corpora callosa, small hippocampi, and disorganized cerebellar folia. Supporting biallelic inheritance for LoF variants, disruption of mouse Clcn3 results in drastic neurodegeneration with loss of the hippocampus a few months after birth and early retinal degeneration. Clcn3−/− mice display severe neurodegeneration, whereas heterozygous Clcn3+/− mice appear normal.

Patch-clamp studies were used to investigate four of the missense variants. These suggested a gain of function in two variants with increased current in HEK cells, however they also showed reduced rectification of voltage and a loss of transient current, plus decreased current amplitude, glycosylation and surface expression when expressed in oocytes, and were suspected to interfere with channel gating and a negative feedback mechanism. These effects were also shown to vary depending on pH levels. The current of the remaining two variants did not differ from WT. For heterozygous missense variants, the disruption induced may be at least partially conferred to mutant/WT homodimers and mutant/ClC-4 heterodimers.

Both loss and gain of function in this gene resulted in the same phenotype.

Cone dystrophy
-------------------
PMID: 33891002 - Khol et al 2021 - report 3 unrelated families with duplications of a region covering the genes IRX5 and IRX6 completely, and the proximal exons of MMP2 and cone dystrophy. They propose that overexpression of IRX5 and IRX6 may be the cause of the disease, and this is supported by expression analysis in patient-derived fibroblasts and zebrafish experiments.

Initial family is a large 5 generation German family with 14 members with autosomal dominant cone dystrophy in which a 600kb duplicated region covering IRX5/IRX6 and part of MMP2 was identified. 2 additional families of Chinese and Dutch descent with copy number gains of ~700 and ~850 kb, covering the same region were then identified. The smallest region of overlap is 608kb. In addition another family of German decent is reported with adCD and the same duplication as the first German family. It is not known if they are distantly related. Segregation analysis on available members of all families showed the duplication in affected members and not in unaffected.

They find that IRX5, IRX6 and MMP2 are expressed in human adult retina. Several lincRNA within the locus are also expressed. In patient derived fibroblasts IRX5 and IRX6 showed increased expression levels. Over expression of IRX5 and IRX6 results in impaired visual performance in zebrafish larvae.; to: Associated with Hamamy syndrome #611174 (AR) in OMIM.

Impaired visual acuity comes to medical attention in early life and vision rapidly deteriorates. Retinal changes are diagnosed as retinitis pigmentosa or pigmentary retinal degeneration on funduscopic examination and as cone-rod dystrophy on ERG. Radiologic hallmarks include short ribs with flared and cupped anterior ends, mild spondylar dysplasia, lacy iliac crests, and metaphyseal irregularities essentially confined to the proximal femora. At least 7 unrelated families reported.

All affected individuals presented with a progressive neurodevelopmental disorder consisting of cognitive impairment, cerebellar atrophy/hypoplasia, motor dysfunction with ataxia and dystonia, and nystagmus. Zebrafish disease modelling supports the involvement of VPS41 dysfunction in the disorder, indicating lysosomal dysregulation throughout the brain and providing support for cerebellar and microglial abnormalities when vps41 was mutated. This provides the first example of human disease linked to the HOPS-specific subunit VPS41 and suggests the importance of HOPS complex activity for cerebellar function."; to: "Five unrelated families with nine affected individuals, all carrying homozygous variants in VPS41 that we show impact protein function.

"Affected individuals were born after uneventful pregnancies and presented in most cases early in life with developmental delay. Various degrees of ataxia, hypotonia, and dystonia were present in all affected individuals, preventing independent ambulation. Likewise, nystagmus was commonly described. In addition, all affected individuals displayed intellectual disability and speech delay. Two siblings further presented with therapy-resistant epilepsy. No major dysmorphic features were found. In two individuals, retinal pigment alterations were noticed. Brain MRI revealed mild cerebellar atrophy and vermian atrophy without other major structural abnormalities in most affected individuals while in one case (Subject 9) bilateral hyperintensities at the nucleus caudatus area were noted. No hearing or vision problems were noted and in cases where nerve conduction studies were performed, these were normal. Transmission electron microscopy (TEM) on peripheral blood lymphocytes from Subject 2 and lymphoblastoid cells from Subject 3 revealed more multilayered vesicles compared to control cells."

Added comment: 2 unrelated patients with mild oculocutaneous albinism, moderate bleeding diathesis, platelet aggregation deficit, and a dramatically decreased number of platelet dense granules, all signs compatible with HPS. Identified distinct homozygous variants in the BLOC1S5 gene (patient 1: deletion of exons 3 and 4, patient 2: 1-bp deletion in exon 4). Parental segregation confirmatory in patient 1, quantitative PCR analysis confirmatory in patient 2). Functional tests performed on platelets of one patient displayed an absence of the obligate multisubunit complex BLOC-1, showing that the variant disrupts BLOC1S5 function and impairs BLOC-1 assembly. Expression of the patient-derived BLOC1S5 deletion in nonpigmented murine Bloc1s5-/- melan-mu melanocytes failed to rescue pigmentation, the assembly of a functional BLOC-1 complex, and melanosome cargo trafficking, unlike the wild-type allele. Pathogenic variants in the genes encoding three other BLOC-1 subunits (DTNBP1, BLOC1S3, and BLOC1S6) underlie HPS types 7, 8, and 9 respectively.

Added comment: Seven individuals from 5 unrelated families reported with severe progeroid form of MAD with growth retardation, small viscerocranium with mandibular underdevelopment, distal acro-osteolyses, lipodystrophy, altered skin pigmentation, renal focal glomerulosclerosis, and extremely severe hypertension in most cases, eventually associated with disseminated arterial calcification. Loss of MTX2 in patients' primary fibroblasts led to loss of Metaxin-1 (MTX1) and mitochondrial dysfunction, including network fragmentation and oxidative phosphorylation impairment. Furthermore, patients' fibroblasts were resistant to induced apoptosis, leading to increased cell senescence and mitophagy and reduced proliferation.
