Discrepant reviews for NBN:Rated as Green by WWMGLH, NWGLH - Amber rating by YNEGLH, LSGLH. To be discussed at July workshop to agree rating. As noted by LSGLH -not sure if this should be in Cytopenia panel – would this not be picked up on chromosome breakage? Then better to go for the single gene test R259.
