Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 0P and 0B.

This summary comes from the ClinGen Evidence Repository: NM_001033855.3(DCLRE1C):c.350C>T is a missense variant predicted to cause substitution of Proline by Leucine at amino acid 117 (p.Pro117Leu). The filtering allele frequency (the upper threshold of the 95% CI of 50/1178836) of the c.350C>T variant in DCLRE1C is 0.00003376 for European (non-Finnish) chromosomes by gnomAD v4, which is higher than the ClinGen SCID VCEP threshold (<0.00003266) for PM2_Supporting, and therefore do not meet this criterion.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 (specification version 1.0): No criteria were applied.

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]

Severe combined immunodeficiency due to DCLRE1C deficiency

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Sep 26, 2021	This sequence change replaces proline with leucine at codon 117 of the DCLRE1C protein (p.Pro117Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine. This variant is present in population databases (rs757316102, ExAC 0.003%). This variant has not been reported in the literature in individuals affected with DCLRE1C-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
Uncertain significance, reviewed by expert panel	curation	ClinGen Severe Combined Immunodeficiency Variant Curation Expert Panel, ClinGen	Feb 15, 2024	NM_001033855.3(DCLRE1C):c.350C>T is a missense variant predicted to cause substitution of Proline by Leucine at amino acid 117 (p.Pro117Leu). The filtering allele frequency (the upper threshold of the 95% CI of 50/1178836) of the c.350C>T variant in DCLRE1C is 0.00003376 for European (non-Finnish) chromosomes by gnomAD v4, which is higher than the ClinGen SCID VCEP threshold (<0.00003266) for PM2_Supporting, and therefore do not meet this criterion. 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 (specification version 1.0): No criteria were applied. -

Variant summary: DCLRE1C c.350C>T (p.Pro117Leu) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.8e-05 in 251150 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.350C>T in individuals affected with Severe Combined Immunodeficiency and no experimental evidence demonstrating its impact on protein function have been reported. Two ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance and one ClinVar submitter (evaluation after 2014) cites it as likely pathogenic. Based on the evidence outlined above, the variant was classified as uncertain significance. -
