Clinical Description OMIM Rotthier et al. (2010) reported 4 unrelated probands with hereditary sensory neuropathy. Three probands had adult onset (ages 38, 37, and 52 years) of distal sensory loss. The presenting symptoms in these patients included loss of touch and ...
Molecular genetics OMIM In a study of 78 unrelated patients with HSAN, Rotthier et al. (2010) found that 4 had heterozygous mutations in the SPTLC2 gene (605713.0001-605713.0003). The mother of 1 of the patients, who also carried the mutation, had some ...
