Genes affected
GAB1 (HGNC:4066): (GRB2 associated binding protein 1) The protein encoded by this gene is a member of the IRS1-like multisubstrate docking protein family. It is an important mediator of branching tubulogenesis and plays a central role in cellular growth response, transformation and apoptosis. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 05, 2024The c.637T>G (p.C213G) alteration is located in exon 4 (coding exon 4) of the GAB1 gene. This alteration results from a T to G substitution at nucleotide position 637, causing the cysteine (C) at amino acid position 213 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
