Genes affected
IGF2BP2 (HGNC:28867): (insulin like growth factor 2 mRNA binding protein 2) This gene encodes a protein that binds the 5' UTR of insulin-like growth factor 2 (IGF2) mRNA and regulates its translation. It plays an important role in metabolism and variation in this gene is associated with susceptibility to diabetes. Alternative splicing and promoter usage results in multiple transcript variants. Related pseudogenes are found on several chromosomes. [provided by RefSeq, Sep 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2023The c.461A>G (p.Y154C) alteration is located in exon 6 (coding exon 6) of the IGF2BP2 gene. This alteration results from a A to G substitution at nucleotide position 461, causing the tyrosine (Y) at amino acid position 154 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
