Genes affected

MFHAS1 (HGNC:16982): (multifunctional ROCO family signaling regulator 1) Identified in a human 8p amplicon, this gene is a potential oncogene whose expression is enhanced in some malignant fibrous histiocytomas (MFH). The primary structure of its product includes an ATP/GTP-binding site, three leucine zipper domains, and a leucine-rich tandem repeat, which are structural or functional elements for interactions among proteins related to the cell cycle, and which suggest that overexpression might be oncogenic with respect to MFH.

The c.2479A>T (p.M827L) alteration is located in exon 1 (coding exon 1) of the MFHAS1 gene. This alteration results from a A to T substitution at nucleotide position 2479, causing the methionine (M) at amino acid position 827 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
