Moreover, 2 hereditary sensory and autonomic neuropathies type 1 (HSANI)-associated mutations of ATL3 (Tyr192Cys and Pro338Arg) impair ATL3's binding to GABARAP and function in reticulophagy.
The same mutation (p.Tyr192Cys) was identified in a second family with similar clinical outcome by screening a large cohort of 115 patients with hereditary sensory and autonomic neuropathies.
We overexpressed the c.2T>C; p.(Met1Thr) mutant in human cell lines and we describe its impact on protein structure and function in comparison with other HSAN-related mutations.
These findings were genetically confirmed by the identification of a nuclear HSAN family which showed segregation of the G387A variant as a non-synonymous SNP.
