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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2023The c.2695C>A (p.Q899K) alteration is located in exon 21 (coding exon 21) of the GIGYF1 gene. This alteration results from a C to A substitution at nucleotide position 2695, causing the glutamine (Q) at amino acid position 899 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
