Genes affected

FASN (HGNC:3594): (fatty acid synthase) The enzyme encoded by this gene is a multifunctional protein. Its main function is to catalyze the synthesis of palmitate from acetyl-CoA and malonyl-CoA, in the presence of NADPH, into long-chain saturated fatty acids. In some cancer cell lines, this protein has been found to be fused with estrogen receptor-alpha (ER-alpha), in which the N-terminus of FAS is fused in-frame with the C-terminus of ER-alpha.

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 2509 of the FASN protein (p.Arg2509Gln). This variant is present in population databases (rs759790350, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with FASN-related conditions. ClinVar contains an entry for this variant (Variation ID: 1052690). 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. -
