L456P (p.Leu456Pro) variant of CBS (Cystathionine beta-synthase)
L456P (p.Leu456Pro) in CBS (Cystathionine beta-synthase) is a missense change. Clinical records from ClinVar, EBI, and UniProt describe it as likely pathogenic in the context of HYPERHOMOCYSTEINEMIA, THROMBOTIC, CBS-RELATED; Classic homocystinuria. The available variant effect predictions contribute to a CATVariant prioritization score of 0.73 / 1. The record also includes experimental measurements, published literature, and structural context.
