Phenotypes for gene: DAGLA were set to Neuroocular syndrome 2, paroxysmal type, MIM# 168885
Review for gene: DAGLA was set to GREEN
Added comment: 9 individuals from 8 families reported with daily paroxysmal spells characterized by eye deviation or nystagmus with abnormal head posturing apparent from birth or early infancy. The episodes tend to be triggered after sleeping, and most patients show improvement of the ocular symptoms over time. Affected individuals also have hypotonia, mild developmental delay, dysarthria, and gait ataxia; most have mildly impaired intellectual development. Seizures are not observed.

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”.

Review for gene: TPP2 was set to GREEN
Added comment: Immunodeficiency-78 with autoimmunity and developmental delay (IMD78) is an autosomal recessive systemic disorder characterized by onset of symptoms in early childhood. Affected individuals present with features of immune deficiency, such as recurrent sinopulmonary or skin infections, as well as autoimmunity, including autoimmune cytopenias, hemolytic anemia, and thrombocytopenia. Autoimmune hepatitis or thyroid disease and central nervous system vasculitis with stroke may also occur. There is increased susceptibility to bacterial, viral, and fungal infections. Laboratory studies show lymphopenia with advanced differentiation and premature senescence of CD8+ T cells and B cells; some patients may have hypergammaglobulinemia. The findings indicate immune dysregulation. Patients also have global developmental delay with speech delay and variable intellectual disability. Five unrelated families and a mouse model.
