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]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004437566).
• BP6: Variant 1-113912120-A-T is Benign according to our data. Variant chr1-113912120-A-T is described in ClinVar as [Benign]. Clinvar id is 533713.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-113912120-A-T is described in Lovd as [Likely_benign].
• BS2: High Homozygotes in GnomAdExome4 at 14 AR gene
