Genes affected

INPPL1 (HGNC:6080): (inositol polyphosphate phosphatase like 1) The protein encoded by this gene is an SH2-containing 5'-inositol phosphatase that is involved in the regulation of insulin function. The encoded protein also plays a role in the regulation of epidermal growth factor receptor turnover and actin remodelling. Additionally, this gene supports metastatic growth in breast cancer and is a valuable biomarker for breast cancer. [provided by RefSeq, Jan 2009]

This sequence change replaces glutamine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 17 of the INPPL1 protein (p.Gln17Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with INPPL1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1956757). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
