Genes affected
IRS4 (HGNC:6128): (insulin receptor substrate 4) IRS4 encodes the insulin receptor substrate 4, a cytoplasmic protein that contains many potential tyrosine and serine/threonine phosphorylation sites. Tyrosine-phosphorylated IRS4 protein has been shown to associate with cytoplasmic signalling molecules that contain SH2 domains. The IRS4 protein is phosphorylated by the insulin receptor tyrosine kinase upon receptor stimulation.. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2023The c.3040G>A (p.G1014S) alteration is located in exon 1 (coding exon 1) of the IRS4 gene. This alteration results from a G to A substitution at nucleotide position 3040, causing the glycine (G) at amino acid position 1014 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
