Genes affected
DCLRE1B (HGNC:17641): (DNA cross-link repair 1B) DNA interstrand cross-links prevent strand separation, thereby physically blocking transcription, replication, and segregation of DNA. DCLRE1B is one of several evolutionarily conserved genes involved in repair of interstrand cross-links (Dronkert et al., 2000 [PubMed 10848582]).[supplied by OMIM, Mar 2008]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jul 03, 2019 | 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. 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"). This variant has not been reported in the literature in individuals with DCLRE1B-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with isoleucine at codon 298 of the DCLRE1B protein (p.Val298Ile). The valine residue is moderately conserved and there is a small physicochemical difference between valine and isoleucine. - |
