Mendeliome v1.2099 UBTF Zornitza Stark edited their review of gene: UBTF: Added comment: PMID 39366741: 3 Chinese patients with global developmental delay, intellectual disability, social challenges and dysmorphism (wide forehead, sparse eyebrows, hypertelorism, narrow palpebral fissures, single-fold eyelids, flat nasal bridge, anteverted nares, a long philtrum and a thin upper lip), but no neuroregression (but aged 1.8yrs-4.8yrs). WES with SNV/CNV analysis showed:
-nonsense variant c.1327C>T p. (Arg443Ter) - parental segregation not possible
-de novo ~46 kb deletion at 17q21.31 containing 7 genes but UBTF as only OMIM Morbid gene
-de novo ~106kb deletion at 17q21.31 containing 10 genes but UBTF as only relevant OMIM Morbid gene (other one was SLC4A1)

Propose haploinsufficiency presents with different phenotype to CONDBA which is due to GOF variant.

Added comment: PMID: 36044892; Twelve different variants reported in 23 affected individuals from 15 unrelated families with biallelic variants. All individuals had global developmental delay and intellectual disability. Consistent facial dysmorphisms included coarse facies, prominent forehead, board depressed nasal root, tented mouth, long smooth philtrum, and low-set ears. In vitro studies of missense variants demonstrated accelerated protein degradation via the autophagy-lysosomal pathway, while analysis of primary fibroblasts and granulocytes provided functional evidence of ER and nuclear envelope dysfunction.

Added comment: 4 individuals from 2 unrelated consanguineous families (Turkish and Indian) reported with a homozygous missense and an NMD-predicted nonsense variant. Affected individuals had features of mucopolysaccharidosis such as short stature, coarse facial features and dysostosis multiplex. Urinary GAG excretion was normal by conventional methods, but LC-MS/MS in 2 individuals revealed an increase in specific dermatan sulfate-derived disaccharides. Functional studies showed reduced protein levels and reduced enzyme activity for the nonsense and missense variant respectively.

A mouse model also shows a mucopolysaccharidosis phenotype, albeit milder.

Rated green (2 families, functional evidence, mouse model).

Mendeliome v0.10044 ECM1 Zornitza Stark changed review comment from: PMID: 11929856 - Hamada et al 2002 - looked at 6 different unrelated consanguineous families (from Saudi Arabia, Kuwait, Pakistan, The Netherlands, UK, and a group of South African families with a probable common ancestor) with a clinical diagnosis of Lipoid proteinosis (LP)/Urbach–Wiethe disease. They performed a genome-wide linkage analysis and identified a region and then looked at the expression of candidate genes in fibroblasts from patients compared to controls. ECM1 was found to have lower expression levels. 6 homozygous deletion variants were identified in the patients. In one family they established that the parents were heterozygous for the variant.

PMID: 28720532 - Afifi et al 2017 - studied 12 patients from 10 unrelated consanguineous Egyptian families with a clinical diagnosis of lipoid proteinosis. The patients reported progressive hoarseness of voice and easily damaged skin by minor trauma or friction. Homozygous ECM1 variants were detected in affected members in all families: 1 family had a missense variant, 5 families had splice site variants and 4 families had indels predicted to cause frameshifts. Parents were found to be heterozygous for the variants.

Classic features include beaded eyelid papules and laryngeal infiltration leading to hoarseness. The disorder is clinically heterogeneous, with affected individuals displaying differing degrees of skin scarring and infiltration, variable signs of hoarseness and respiratory distress, and in some cases neurologic abnormalities such as temporal lobe epilepsy. Histologically, there is widespread deposition of hyaline (glycoprotein) material and disruption/reduplication of basement membrane

Mendeliome v0.2758 CDC42BPB Zornitza Stark gene: CDC42BPB was added
gene: CDC42BPB was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: CDC42BPB was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: CDC42BPB were set to 32031333
Phenotypes for gene: CDC42BPB were set to Central hypotonia; Global developmental delay; Intellectual disability; Seizures; Autistic behavior; Behavioral abnormality
Review for gene: CDC42BPB was set to GREEN
Added comment: 14 individuals with missense and loss-of-function CDC42BPB variants reported. Features included hypotonia (8/11), DD (12/13 - the 14th was a fetus), ID (7/13), ASD (8/12), clinical seizures (in 3 - a 4th had abnormal EEG without seizures), behavioral abnormalities. Variable non-specific dysmorphic features were reported in some (sparse hair being the most frequent - 4/8). Additional features were observed in few (=<4) incl. cryptorchidism, ophthalmological issues, constipation, kidney abnormalities, micropenis, etc. Most variants occurred as de novo events (11/14) while inheritance was not available for few (3/14).
