Genes affected

UQCRHL (HGNC:51714): (ubiquinol-cytochrome c reductase hinge protein like) This gene has characteristics of a pseudogene derived from the UQCRH gene. However, there is still an open reading frame that could produce a protein of the same or nearly the same size as that of the UQCRH gene, so this gene is being called protein-coding for now.

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.40225914).

The c.85C>T (p.P29S) alteration is located in exon 1 (coding exon 1) of the UQCRHL gene. This alteration results from a C to T substitution at nucleotide position 85, causing the proline (P) at amino acid position 29 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
