Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004788362 SCV005400155 uncertain significance Neurodevelopmental disorder 2023-07-17 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3B. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with nephrotic syndrome (MONDO#0005377), ITSN1-related, and neurodevelopmental disorder (MONDO#0700092), ITSN1-related. (I) 0108 - This gene is associated with both recessive and dominant disease. Biallelic variants cause autosomal recessive nephrotic syndrome (MONDO#0005377), ITSN1-related, while monoallelic variants cause autosomal dominant neurodevelopmental disorder (MONDO#0700092), ITSN1-related (PMIDs: 29773874, 30721404, 34707297). (I) 0200 - Variant is predicted to result in a missense amino acid change from asparagine to aspartic acid. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.01 (1 heterozygote, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2) (1 heterozygote, 0 homozygotes). (I) 0503 - Missense variant consistently predicted to be tolerated by multiple in silico tools or not conserved in placental mammals with a minor amino acid change. (SB) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1207 - Parental origin of the variant is unresolved. This variant has been proven to not be maternally inherited (by duo analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
