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.

The c.2992C>T (p.P998S) alteration is located in exon 23 (coding exon 23) of the GIGYF1 gene. This alteration results from a C to T substitution at nucleotide position 2992, causing the proline (P) at amino acid position 998 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
