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.

Sep 20, 2023

The c.2944G>A (p.A982T) alteration is located in exon 23 (coding exon 23) of the GIGYF1 gene. This alteration results from a G to A substitution at nucleotide position 2944, causing the alanine (A) at amino acid position 982 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
