Genes affected

GIGYF1 (HGNC:9126): (GRB10 interacting GYF protein 1) This gene encodes a member of the gyf family of adaptor proteins. The encoded protein contains a gyf protein interaction domain. It binds growth factor receptor bound 10, another adaptor protein that binds activated insulin-like growth factor 1 and insulin receptors and regulates receptor signaling.

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A. Following criteria are met: 0105 - The mechanism of disease for this gene is not clearly established. However, loss of function is unlikely to be associated with neurodevelopmental disorder, GIGYF1-related (MONDO#0700092; PMID: 33057194; PMID: 34732801; PMID: 34234147). (I) 0107 - This gene is associated with autosomal dominant disease (PMID: 33057194). (I) 0200 - Variant is predicted to result in a missense amino acid change from proline to leucine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 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) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed, by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
