Genes affected

IGF2BP1 (HGNC:28866): (insulin like growth factor 2 mRNA binding protein 1) This gene encodes a member of the insulin-like growth factor 2 mRNA-binding protein family. The protein encoded by this gene contains four K homology domains and two RNA recognition motifs. It functions by binding to the mRNAs of certain genes, including insulin-like growth factor 2, beta-actin and beta-transducin repeat-containing protein, and regulating their translation. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]

The c.1076G>A (p.S359N) alteration is located in exon 9 (coding exon 9) of the IGF2BP1 gene. This alteration results from a G to A substitution at nucleotide position 1076, causing the serine (S) at amino acid position 359 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
