Genes affected
NSF (HGNC:8016): (N-ethylmaleimide sensitive factor, vesicle fusing ATPase) Enables PDZ domain binding activity and ionotropic glutamate receptor binding activity. Involved in intracellular protein transport; positive regulation of protein catabolic process; and positive regulation of receptor recycling. Located in Golgi apparatus; cytosol; and plasma membrane. Implicated in developmental and epileptic encephalopathy. [provided by Alliance of Genome Resources, Apr 2022]
LRRC37A2 (HGNC:32404): (leucine rich repeat containing 37 member A2) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

Uncertain significance, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJun 18, 2024Variant summary: NSF c.1814T>C (p.Ile605Thr) results in a non-conservative amino acid change located in the AAA+ ATPase domain (IPR003593) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 249482 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1814T>C in individuals affected with Developmental And Epileptic Encephalopathy 96 and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as uncertain significance. -
