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 GeneticsMay 09, 2022The c.175A>G (p.I59V) alteration is located in exon 2 (coding exon 2) of the GAB1 gene. This alteration results from a A to G substitution at nucleotide position 175, causing the isoleucine (I) at amino acid position 59 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
