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]

MEIG1 (HGNC:23429): (meiosis/spermiogenesis associated 1) Predicted to act upstream of or within cellular protein localization; manchette assembly; and sperm axoneme assembly. Predicted to be located in cytosol and manchette. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
