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]
IRS4-AS1 (HGNC:55650): (IRS4 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2022The c.154G>A (p.G52R) 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 154, causing the glycine (G) at amino acid position 52 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
