Labcorp Genetics (formerly Invitae), Labcorp RCV000116203 SCV003443405 pathogenic Glycogen storage disease due to muscle and heart glycogen synthase deficiency 2023-03-08 criteria provided, single submitter clinical testing This variant is present in population databases (rs587777375, gnomAD 0.03%). This sequence change creates a premature translational stop signal (p.Asp56Argfs*108) in the GYS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GYS1 are known to be pathogenic (PMID: 17928598, 19699667). This premature translational stop signal has been observed in individual(s) with clinical features of glycogen synthase deficiency (PMID: 19699667). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 128236).
