Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_004225.3(MFHAS1):​c.2839G>T​(p.Ala947Ser) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A947P) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: MFHAS1 NM_004225.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.62
• Publications: 0 publications found

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.
