Associated disorders

The HINT1 gene is associated with autosomal recessive neuromyotonia and axonal neuropathy (NMAN) (MedGen UID: 449355).

The percentage of clinical cases of autosomal recessive neuromyotonia and axonal neuropathy (NMAN) caused by pathogenic variants in the HINT1 gene is unknown, however, HINT1 is most frequent cause of dHMN in Czech populations.

The HINT1 gene encodes the histidine triad nucleotide-binding protein 1. HINT1 has a functional role in neurons, where it appears to stabilize the interaction of different receptors and regulate the effects of their signaling.

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.
