Submissions by phenotype
Aplastic anemia Pathogenic:2
This sequence change replaces arginine with a termination signal at codon 218 of the SBDS protein (p.Arg218Ter). Null variant (nonsense), in gene SBDS, for which loss-of-function is a known mechanism of disease (associated with Shwachman-Diamond syndrome 1 and Aplastic anemia. ClinVar classifies this variant as Pathogenic, rated 0 stars, no assertion criteria provided, with 1 submission, 1 publication (15284109). In-silico prediction models show pathogenic computational verdict based on 4 pathogenic predictions from BayesDel_addAF, DANN, FATHMM-MKL and MutationTaster vs 1 benign prediction from EIGEN. Therefore, this variant is classified as likely pathogenic. -
