Genes affected

SUPV3L1 (HGNC:11471): (Suv3 like RNA helicase) Enables helicase activity; nucleic acid binding activity; and protein homodimerization activity. Involved in several processes, including mitochondrial RNA metabolic process; mitochondrion morphogenesis; and positive regulation of mitochondrial RNA catabolic process. Located in mitochondrial nucleoid and nucleus. Part of mitochondrial degradosome. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.303 is higher than 0.05.
