Genes affected

UQCC6 (HGNC:34450): (ubiquinol-cytochrome c reductase complex assembly factor 6) Involved in mitochondrial respiratory chain complex III assembly. Located in mitochondrial inner membrane. [provided by Alliance of Genome Resources, Apr 2022]

HSP90B1 (HGNC:12028): (heat shock protein 90 beta family member 1) This gene encodes a member of a family of adenosine triphosphate(ATP)-metabolizing molecular chaperones with roles in stabilizing and folding other proteins. The encoded protein is localized to melanosomes and the endoplasmic reticulum. Expression of this protein is associated with a variety of pathogenic states, including tumor formation. There is a microRNA gene located within the 5' exon of this gene. There are pseudogenes for this gene on chromosomes 1 and 15. [provided by RefSeq, Aug 2012]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.968 is higher than 0.05.
