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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1739C>T (p.P580L) alteration is located in exon 14 (coding exon 14) of the DCLRE1C gene. This alteration results from a C to T substitution at nucleotide position 1739, causing the proline (P) at amino acid position 580 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 580 of the DCLRE1C protein (p.Pro580Leu). This variant is present in population databases (rs780103215, gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DCLRE1C-related conditions. ClinVar contains an entry for this variant (Variation ID: 235552). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
