Genes affected

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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_001033855.3. Strenght limited to Supporting due to length of the change: 1aa.
• BP6: Variant 10-14909099-ACTT-A is Benign according to our data. Variant chr10-14909099-ACTT-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 430113.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000217 (33/152330) while in subpopulation EAS AF= 0.00154 (8/5186). AF 95% confidence interval is 0.000767. There are 0 homozygotes in gnomad4. There are 17 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.

The c.1385_1387delAAG variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The variant is observed in 26/8652 (0.301%) alleles from individuals of East Asian background in the ExAC dataset (Lek et al., 2016). The variant results in the in-frame deletion of Glutamic acid 462, a residue which is not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. In summary, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
