KIF1A

Alias

ATSV; C2orf20; HSN2C; MRD9; SPG30; UNC104

Associated disorders

The KIF1A gene is associated with autosomal recessive hereditary sensory neuropathy type 2C (HSN2C) (MedGen UID: 481798) and spastic paraplegia 30 (SPG30) (MedGen UID: 372152). The KIF1A gene is also associated with autosomal dominant complicated spastic paraplegia and intellectual disability 9 (ID9) (MedGen UID: 481913; PMID: 25265257).

Pathogenic variants in KIF1A are a rare cause of hereditary sensory and autonomic neuropathy.

The KIF1A gene encodes the protein kinesin family member 1A. Kinesins are motor proteins that transport organelles and other cargo throughout the cell. KIF1A is involved in transport of organelles along axonal microtubules.

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.
