Genes affected

TEX38 (HGNC:29589): (testis expressed 38) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

ATPAF1 (HGNC:18803): (ATP synthase mitochondrial F1 complex assembly factor 1) This gene encodes an assembly factor for the F(1) component of the mitochondrial ATP synthase. This protein binds specifically to the F1 beta subunit and is thought to prevent this subunit from forming nonproductive homooligomers during enzyme assembly. Alternatively spliced transcript variants have been identified. [provided by RefSeq, Aug 2011]

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.27686286).
