Description

The BCKDHB c.360dupT variant is predicted to result in premature protein termination (p.Asn121*). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0065% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/6-80877406-G-GT). Nonsense variants in BCKDHB are expected to be pathogenic. This variant is interpreted as likely pathogenic.
