Genes affected
STAC3 (HGNC:28423): (SH3 and cysteine rich domain 3) The protein encoded by this gene is a component of the excitation-contraction coupling machinery of muscles. This protein is a member of the Stac gene family and contains an N-terminal cysteine-rich domain and two SH3 domains. Mutations in this gene are a cause of Native American myopathy.

Bailey-Bloch congenital myopathy Pathogenic:2Other:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 13, 2023This sequence change creates a premature translational stop signal (p.Lys288*) in the STAC3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in STAC3 are known to be pathogenic (PMID: 28411587, 28777491). This variant is present in population databases (rs371720347, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with congenital myopathy (PMID: 28411587). ClinVar contains an entry for this variant (Variation ID: 425007). For these reasons, this variant has been classified as Pathogenic. -
