Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_006012.4(CLPP):c.100C>T(p.Pro34Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000112 in 1,442,702 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P34L) has been classified as Uncertain significance.

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: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.03057614).

BP6

Variant 19-6361674-C-T is Benign according to our data. Variant chr19-6361674-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 505534.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000113 (146/1290374) while in subpopulation MID AF = 0.00735 (38/5172). AF 95% confidence interval is 0.0055. There are 1 homozygotes in GnomAdExome4. There are 66 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
