The ACTA1 gene is associated with autosomal dominant and recessive nemaline myopathy 3 (NEM3) (MedGen UID: 371799) and autosomal dominant congenital fiber-type disproportion (CFTD) (MedGen UID: 108177). Other ACTA1-related disorders have also been reported (OMIM# 102610).

Invitae tests that include this gene:
ACTA1 accounts for approximately 15%-25% of nemaline myopathy. Pathogenic variants in ACTA1are more prevalent in severe neonatal-onset cases.
ACTA1 encodes alpha-actin, the main actin of skeletal muscle. Alpha-actin is found along the sarcomeric thin filament where it binds to thick filament myosin to generate contractile force. Alpha-actin binds many other proteins, notably nebulin, along the thin filament.
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
