Added comment: Wang paper PMID: 37943610

SEL1L protein is involved in the SEL1L-HRD1 endoplasmic reticulum (ER)-associated degradation.

Report two biallelic missense variants in SEL1L in six children from three independent families presenting with developmental delay, intellectual disability, microcephaly, facial dysmorphisms, hypotonia and/or ataxia (termed ERAD-associated neurodevelopment disorder with onset in infancy (ENDI). The variants were hypomorphic and impaired ERAD function.

Identified by WES. Parents heterozygous and asymptomatic. P.(Gly585Asp) in Patient 1, p.(Met528Arg) in Patients 2 and 3 (siblings).

All variants cause substrate accumulation. The extent of substrate accumulation in knockin cells was modest compared to those in knockout cells, pointing to a hypomorphic nature.

They also had a variant in HRD1.



Weis paper PMID: 37943617

Third variant p.(Cys141Tyr), biallelic, causing premature death in five patients from a consanguineous family with early-onset neurodevelopmental disorders and agammaglobulinaemia due to severe SEL1L-HRD1 ERAD dysfunction.

This variant appears to have a more severe outcome, exhibiting B cell depletion and agammaglobulinaemia, causing the most severe dysfunction among all of the variants described by this group so far. They postulate that functionality of SEL1L-HRD1 ERAD is inversely correlated with disease severity in humans.

Their symptoms were dev delay, neurological disorder and agammaglobulinaemia in childhood. Along with severe axial hypotonia, short stature and microcephaly.

“Not a complete loss-of-function variant”.

Mendeliome v1.547 IL2RB Zornitza Stark changed review comment from: Five families reported.
Sources: Expert list; to: Five families reported.

Affected individuals present in infancy with features of both abnormal activation of certain immune signaling pathways, resulting in lymphoid proliferation, dermatitis, enteropathy, and hypergammaglobulinemia, as well as features of immunodeficiency, such as recurrent infections and increased susceptibility to viral infections, especially CMV. Laboratory studies show increased NK cells that show impaired differentiation, as well as abnormal T cell populations or responses. Some patients may die in childhood; hematopoietic bone marrow transplantation is curative.

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.

Mendeliome v0.7004 PRIM1 Zornitza Stark changed review comment from: - PMID: 33060134 (2020) - From a cohort of 220 families with microcephalic dwarfism spectrum disorders (OFC ≤−4 SD; height ≤−2 SD), three families (4 individuals) were identified with the same homozygous intronic variant (c.638+36C>G) in PRIM1. This variant was present in gnomAD in 2 individuals across all populations, but only in a heterozygous state. Haplotype analysis indicated that all three families share a distant common ancestor - i.e. confirmed founder variant.
Authors subsequently identified a single individual with compound heterozygous PRIM1 variants (c.103+1G>T, c.901T>C) from the DDD study, who also presented microcephaly and short stature (OFC ≤−3 SD; height ≤−3 SD).

Clinical overlap was evident in all 5 individuals, presenting extreme pre- and postnatal growth restriction, severe microcephaly (OFC −6.0 ± 1.5 SD) with simplified gyri appearance, hypothyroidism, hypo/agammaglobulinaemia, and lymphopaenia accompanied by intermittent anaemia/thrombocytopaenia. All had chronic respiratory symptoms, and four died in early childhood from respiratory or GI infections.

Functional studies demonstrated reduced PRIM1 protein levels, replication fork defects and prolonged S-phase duration in PRIM1-deficient cells. The resulting delay to the cell cycle and inability to sustain sufficient cell proliferation provides a likely mechanism for the presenting phenotype.

Added comment: - PMID: 33060134 (2020) - From a cohort of 220 families with microcephalic dwarfism spectrum disorders (OFC ≤−4 SD; height ≤−2 SD), three families (4 individuals) were identified with the same homozygous intronic variant (c.638+36C>G) in PRIM1. This variant was present in gnomAD in 2 individuals across all populations, but only in a heterozygous state. Haplotype analysis indicated that all three families share a distant common ancestor - i.e. confirmed founder variant.
Authors subsequently identified a single individual with compound heterozygous PRIM1 variants (c.103+1G>T, c.901T>C) from the DDD study, who also presented microcephaly and short stature (OFC ≤−3 SD; height ≤−3 SD).

Clinical overlap was evident in all 5 individuals, presenting extreme pre- and postnatal growth restriction, severe microcephaly (OFC −6.0 ± 1.5 SD) with simplified gyri appearance, hypothyroidism, hypo/agammaglobulinemia, and lymphopenia accompanied by intermittent anaemia/thrombocytopenia. All had chronic respiratory symptoms, and four died in early childhood from respiratory or GI infections.

Functional studies demonstrated reduced PRIM1 protein levels, replication fork defects and prolonged S-phase duration in PRIM1-deficient cells. The resulting delay to the cell cycle and inability to sustain sufficient cell proliferation provides a likely mechanism for the presenting phenotype.

Added comment: - PMID: 32181500 (2020) - Three patients from two independent consanguineous families with homozygous variants (c.3353G>A, p.Ser1118Asn and c.1289delA, p.His430Profs7*) in the FNIP1 gene. Both variants segregated with the disease phenotype in each family. Clinically, patients presented with combined immunodeficiency, cardiac findings (hypertrophic cardiomyopathy, Wolff‐Parkinson‐White syndrome), and myopathy of skeletal muscles with motor DD. Authors note phenotypic overlap with the murine model of FNIP1 deficiency, but no functional analyses of the variants or patient cells were performed.

- PMID: 32905580 (2020) - Three cases from unrelated families, all harbouring novel biallelic variants in FNIP1. Clinical manifestations in all patients include hypertrophic cardiomyopathy, severe and/or recurrent infections, absent circulating B-cells, and agammaglobulinemia; as well as either severe or intermittent neutropenia in two cases. Functional studies showed impairment of B-cell metabolism, including disruptions to mitochondrial numbers/activity and the PI3K/AKT pathway.
