Our verdict is Benign. Variant got -15 ACMG points: 2P and 17B. PM2BP4_StrongBP6_Very_StrongBP7BS1
The NM_001033855.3(DCLRE1C):c.1503T>C(p.Asp501Asp) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000444 in 1,614,166 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★).
DCLRE1C (HGNC:17642): (DNA cross-link repair 1C) This gene encodes a nuclear protein that is involved in V(D)J recombination and DNA repair. The encoded protein has single-strand-specific 5'-3' exonuclease activity; it also exhibits endonuclease activity on 5' and 3' overhangs and hairpins. The protein also functions in the regulation of the cell cycle in response to DNA damage. Mutations in this gene can cause Athabascan-type severe combined immunodeficiency (SCIDA) and Omenn syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.62).
BP6
Variant 10-14908984-A-G is Benign according to our data. Variant chr10-14908984-A-G is described in ClinVar as [Benign]. Clinvar id is 137074.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.159 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00247 (376/152354) while in subpopulation AFR AF= 0.00866 (360/41584). AF 95% confidence interval is 0.00792. There are 1 homozygotes in gnomad4. There are 180 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
Review Status: criteria provided, single submitter
Collection Method: clinical testing
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
