Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BS2_SupportingBA1

This summary comes from the ClinGen Evidence Repository: NM_001033855.3(DCLRE1C):c.1284A>C is a missense variant predicted to cause substitution of Lysine by Asparagine at amino acid 428 (p.Lys428Asn).The filtering allele frequency (the lower threshold of the 95% CI of 501/75018) of the c.1284A>C variant in DCLRE1C is 0.005719 for African/African American chromosomes by gnomAD v4, which is higher than the ClinGen SCID VCEP threshold (>0.00346) for BA1, and therefore meets this criterion (BA1). Additionally, 2 homozygous adults are reported in gnomAD v.4 in the same population. BS2_Supporting is Met.In summary, this variant meets the criteria to be classified as Benign for autosomal recessive severe combined immunodeficiency due to DCLRE1C deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID-VCEP: BA1 and BS2_Supporting. (VCEP specifications version 1). LINK:https://erepo.genome.network/evrepo/ui/classification/CA5416508/MONDO:0011225/116

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]
