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]

The c.2884G>A (p.V962I) 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 2884, causing the valine (V) at amino acid position 962 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
