Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BS2_Supporting BA1

This summary comes from the ClinGen Evidence Repository: The NM_001033855.3:c.959C>G variant in DCLRE1C is a missense variant predicted to cause substitution of serine by cysteine at amino acid 320 (p.Ser320Cys). This variant has an allele frequency of 0.03553 in the African / African American population in gnomAD, which is above the threshold for BA1 set by the ClinGen SCID VCEP for DCLRE1C (>0.00346). In addition, 16 adult homozygous individuals with this variant are present in gnomAD v2.1.1 (in African/African American population)(BS2_Supporting).In summary, this variant meets the criteria to be classified as Benign for autosomal recessive SCID based on the ACMG criteria applied: BA1 and BS2_Supporting as specified by the ClinGen SCID VCEP (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]
