Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PM2_Supporting

This summary comes from the ClinGen Evidence Repository: The c.457G>T (NM_001033855.3) variant in DCLRE1C is a missense variant predicted to cause substitution of Glycine by Tryptophan at amino acid 153 (p.Gly153Trp).The filtering allele frequency (the upper threshold of the 95% CI of 8/1111862 alleles) of the c.457G>T variant in DCLRE1C is 0.000003100 for European (non-Finnish) chromosomes by gnomAD v4, which is lower than the ClinGen SCID VCEP threshold (<0.00003266) for PM2_Supporting, and therefore meets this criterion (PM2_Supporting). No homozygotes have been observed in gnomAD.To our knowledge, this variant has not been reported in the literature in individuals affected with SCID/DCLRE1C-related conditions or in functional studies.In summary, this variant meets the criteria to be classified as a variant of uncertain significance for autosomal recessive severe combined immunodeficiency due to DCLRE1C deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP: PM2_Supporting (VCEP specifications version 1).

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]

Jun 12, 2022

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with tryptophan, which is neutral and slightly polar, at codon 153 of the DCLRE1C protein (p.Gly153Trp). This variant is present in population databases (rs41297018, gnomAD 0.01%). 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: 879949). 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 disruptive. 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. -

Significance:Uncertain significance

Review Status:reviewed by expert panel

Collection Method:curation

The c.457G>T (NM_001033855.3) variant in DCLRE1C is a missense variant predicted to cause substitution of Glycine by Tryptophan at amino acid 153 (p.Gly153Trp). The filtering allele frequency (the upper threshold of the 95% CI of 8/1111862 alleles) of the c.457G>T variant in DCLRE1C is 0.000003100 for European (non-Finnish) chromosomes by gnomAD v4, which is lower than the ClinGen SCID VCEP threshold (<0.00003266) for PM2_Supporting, and therefore meets this criterion (PM2_Supporting). No homozygotes have been observed in gnomAD. To our knowledge, this variant has not been reported in the literature in individuals affected with SCID/DCLRE1C-related conditions or in functional studies. In summary, this variant meets the criteria to be classified as a variant of uncertain significance for autosomal recessive severe combined immunodeficiency due to DCLRE1C deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP: PM2_Supporting (VCEP specifications version 1). -

Illumina Laboratory Services, Illumina

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
