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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.1154C>A (p.P385Q) alteration is located in exon 10 (coding exon 10) of the IGF2BP1 gene. This alteration results from a C to A substitution at nucleotide position 1154, causing the proline (P) at amino acid position 385 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
