TOR1AIP1

Alias

LAP1; LAP1B; LGMD2Y

Associated disorders

The TOR1AIP1 gene is associated with autosomal recessive limb-girdle muscular dystrophy type 2Y (LGMD2Y) (MedGen UID: 934698). Additionally, the TOR1AIP1 gene has preliminary evidence supporting a correlation with autosomal recessive dystonia, cerebellar atrophy and cardiomyopathy (PMID: 25425325).

Invitae tests that include this gene:

Pathogenic variants in TOR1AIP1 cause an unknown percentage of limb girdle muscular dystrophy.

The TOR1AIP1 encodes the Torsin A-interacting protein 1, which localizes to the nuclear membrane and interacts with the multifunctional ATPase TOR1A.

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.
