Summary: 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.

Study reports patients with congenital myopathy carrying either a homozygous, heterozygous p.(Trp284Ser) STAC3 variant or a novel splice site change (c.997-1G > T). The patients have distinctive dysmorphic features in addition to a malignant hyperthermia-like in some. These variants showed a defective excitation-contraction which is not a result of CaV 1.1 sarcolemma mislocation or impaired interaction with CaV 1.1.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: REVIEWED

Description

Transcript Variant: This variant (4) lacks four alternate internal exons, compared to variant 1. This variant is represented as non-coding because the use of the expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
