## TL;DR

A new genetic mutation in the DST gene is linked to a rare neurological disorder in two siblings from a Pakistani family.

## Contribution

Identifies a novel homozygous DST variant as a cause of hereditary sensory and autonomic neuropathy type 6.

## Key findings

- A homozygous DST variant was found in two affected siblings with HSAN-VI.
- The DST mutation is associated with the clinical features of HSAN-VI in this family.

## Abstract

Hereditary sensory and autonomic neuropathy type 6 (HSAN-VI) is a rare autosomal recessive neurological disorder that affects fewer than 1 in 1,000,000 individuals worldwide and is characterized by neonatal hypotonia, respiratory and feeding difficulties, impaired motor development and autonomic abnormalities with highly variable age of onset and severity. Here we report a novel homozygous DST variant in association with HSAN-VI in two Pakistani siblings.
