Genes affected

IGF1R (HGNC:5465): (insulin like growth factor 1 receptor) This receptor binds insulin-like growth factor with a high affinity. It has tyrosine kinase activity. The insulin-like growth factor I receptor plays a critical role in transformation events. Cleavage of the precursor generates alpha and beta subunits. It is highly overexpressed in most malignant tissues where it functions as an anti-apoptotic agent by enhancing cell survival. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, May 2014]

ClinVar contains an entry for this variant (Variation ID: 1935292). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with IGF1R-related conditions. This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 10 of the IGF1R protein (p.Pro10Ser). This variant is present in population databases (rs530243293, gnomAD 0.01%). -
