Arina Puzriakova (Genomics England Curator)

Comment on list classification: Relevant phenotype (two unrelated cases with severe congenital microcephaly) but additional cases required before inclusion of RAD50 on a diagnostic panel.

Rating Amber in anticipation of additional publications/clinical evidence (added to watchlist).

Zornitza Stark (Australian Genomics)

Green List (high evidence)

Two individuals reported with bi-allelic variants in this gene showing dysmorphic facial features similar to NBS, short stature, microcephaly, and mild/moderate intellectual disability. Fibroblasts established from one of the individuals showed chromosomal instability and abnormal radioresistant DNA synthesis. The MRE11/RAD50/NBN (MRN) complex is involved in signaling processes inducing the repair of DNA double-strand breaks. Variants in NBN and MRE11 are associated with Nijmegen breakage syndrome (NBS) and ataxia telangiectasia (AT)‐like disorder, respectively, so this gene is a strong biological candidate for this phenotype.
