ANO5

Alias

GDD1; LGMD2L; TMEM16E

Associated disorders

The ANO5 gene is associated with autosomal recessive limb-girdle muscular dystrophy type 2L (LGMD2L) (MedGen UID: 370102) and Miyoshi muscular dystrophy 3 (MMD3) (MedGen UID: 413750). It is also associated with autosomal dominant gnathodiaphyseal dysplasia (GDD) (MedGen UID: 331575).

Pathogenic variants in ANO5 cause an estimated 25% and 11% of cases of autosomal recessive LGMD in the UK and Denmark, respectively. A founder mutation prevalent in Northern Europe makes anoctaminopathy one of the more common forms of LGMD. ANO5 is the only known cause of gnathodiaphyseal dysplasia. ANO5 is also a rare cause of distal myopathy.

The ANO5 gene encodes the Anoctomin 5 protein, a transmembrane protein that is expressed in skeletal and cardiac muscle and may play a role in membrane repair.

Assay and technical information

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.
