Genes affected
CLPP (HGNC:2084): (caseinolytic mitochondrial matrix peptidase proteolytic subunit) The protein encoded by this gene belongs to the peptidase family S14 and hydrolyzes proteins into small peptides in the presence of ATP and magnesium. The protein is transported into mitochondrial matrix and is associated with the inner mitochondrial membrane. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PM1
In a chain ATP-dependent Clp protease proteolytic subunit, mitochondrial (size 220) in uniprot entity CLPP_HUMAN there are 11 pathogenic changes around while only 1 benign (92%) in NM_006012.4
BP4
Computational evidence support a benign effect (MetaRNN=0.1813038).
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.0000985 (15/152234) while in subpopulation AMR AF = 0.000589 (9/15284). AF 95% confidence interval is 0.000307. There are 0 homozygotes in GnomAd4. There are 9 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
