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.

The c.4393G>A (p.G1465S) alteration is located in exon 25 (coding exon 24) of the FASN gene. This alteration results from a G to A substitution at nucleotide position 4393, causing the glycine (G) at amino acid position 1465 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 1465 of the FASN protein (p.Gly1465Ser). This variant is present in population databases (rs763072807, gnomAD 0.01%). 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: 580713). 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. -
