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.

Ambry Genetics

Feb 16, 2023

The c.3087C>G (p.I1029M) alteration is located in exon 24 (coding exon 24) of the GIGYF1 gene. This alteration results from a C to G substitution at nucleotide position 3087, causing the isoleucine (I) at amino acid position 1029 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
