Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 2P and 13B. PM1BP4_StrongBP6BS1BS2

The NM_007272.3(CTRC):c.674A>C(p.Glu225Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000255 in 1,614,184 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. E225E) has been classified as Likely benign.

Genes affected

CTRC (HGNC:2523): (chymotrypsin C) This gene encodes a member of the peptidase S1 family. The encoded protein is a serum calcium-decreasing factor that has chymotrypsin-like protease activity. Alternatively spliced transcript variants have been observed, but their full-length nature has not been determined. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 19 uncertain in NM_007272.3

BP4

Computational evidence support a benign effect (MetaRNN=0.016462207).

BP6

Variant 1-15445631-A-C is Benign according to our data. Variant chr1-15445631-A-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 240766.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000259 (378/1461890) while in subpopulation MID AF = 0.000693 (4/5768). AF 95% confidence interval is 0.000401. There are 1 homozygotes in GnomAdExome4. There are 201 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check.

BS2

High AC in GnomAd4 at 33 AD gene.
