Genes affected

ATP5PO (HGNC:850): (ATP synthase peripheral stalk subunit OSCP) The protein encoded by this gene is a component of the F-type ATPase found in the mitochondrial matrix. F-type ATPases are composed of a catalytic core and a membrane proton channel. The encoded protein appears to be part of the connector linking these two components and may be involved in transmission of conformational changes or proton conductance.

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.991

The c.551G>C (p.G184A) alteration is located in exon 7 (coding exon 7) of the ATP5O gene. This alteration results from a G to C substitution at nucleotide position 551, causing the glycine (G) at amino acid position 184 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
