Genes affected

CLPX (HGNC:2088): (caseinolytic mitochondrial matrix peptidase chaperone subunit X) The protein encoded by this gene is part of a protease found in mitochondria. This protease is ATP-dependent and targets specific proteins for degradation. The protease consists of two heptameric rings of the CLPP catalytic subunit sandwiched between two hexameric rings of the chaperone subunit encoded by this gene. Targeted proteins are unwound by this protein and then passed on to the CLPP subunit for degradation. Two transcript variants, one protein-coding and the other non-protein coding, have been found for this gene. [provided by RefSeq, Nov 2015]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.52).
• BP6: Variant 15-65154806-G-A is Benign according to our data. Variant chr15-65154806-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3010364.Status of the report is criteria_provided_single_submitter, 1 stars.
