Disease characteristics

Excerpted from the GeneReview: SPTLC1-Related Hereditary Sensory Neuropathy
SPTLC1-related hereditary sensory neuropathy (HSN) is an axonal form of hereditary motor and sensory neuropathy distinguished by prominent early sensory loss and later positive sensory phenomena including dysesthesia and characteristic "lightning" or "shooting" pains. Loss of sensation can lead to painless injuries, which, if unrecognized, result in slow wound healing and subsequent osteomyelitis requiring distal amputations. Motor involvement is present in all advanced cases and can be severe. After age 20 years, the distal wasting and weakness may involve proximal muscles, possibly leading to wheelchair dependency by the seventh or eighth decade. Sensorineural hearing loss is variable. [from GeneReviews]

Additional description

From OMIM
Hereditary sensory and autonomic neuropathy type IA (HSAN1A) is an autosomal dominant neurologic disorder characterized by sensory neuropathy with variable autonomic and motor involvement. Most patients have adult onset of slowly progressive distal sensory impairment manifest as numbness, tingling, or pain, as well as distal muscle atrophy. Complications include ulceration and osteomyelitis. Some patients may have a more severe phenotype with onset in childhood. Electrophysiologic studies show a predominantly axonal neuropathy with some demyelinating features. Some patients may have evidence of central nervous system involvement, including macular telangiectasia type 2. Affected individuals have increased levels of plasma 1-deoxysphingolipids (1-deoxySLs), which are thought to be neurotoxic (summary by Rotthier et al., 2010 and Gantner et al., 2019). Oral supplementation with serine decreases 1-deoxySL and may offer some clinical benefits (Fridman et al., 2019). Genetic Heterogeneity of Hereditary Sensory and Autonomic Neuropathy See also HSAN1C (613640), caused by mutation in the SPTLC2 gene (605713) on 14q24; HSN1D (613708), caused by mutation in the ATL1 gene (606439) on 14q22; HSN1E (614116), caused by mutation in the DNMT1 gene (126375) on 19p13; HSN1F (615632), caused by mutation in the ATL3 gene (609369) on 11q13; HSAN2A (201300), caused by mutation in the HSN2 isoform of the WNK1 gene (605232) on 12p13; HSAN2B (613115), caused by mutation in the FAM134B gene (613114) on 5p15; HSN2C (614213), caused by mutation in the KIF1A gene (601255) on 2q37; HSAN2D (see 243000), caused by mutation in the SCN9A gene (603415) on 2q24; HSAN3 (223900), caused by mutation in the ELP1 gene (603722) on 9q31; HSAN4 (256800), caused by mutation in the NTRK1 gene (191315) on 1q23; HSAN5 (608654), caused by mutation in the NGF gene (162030) on 1p13; HSAN6 (614653), caused by mutation in the DST gene (113810) on 6p12; HSAN7 (615548), caused by mutation in the SCN11A gene (604385) on 3p22; and HSAN8 (616488), caused by mutation in the PRDM12 gene (616458) on chromosome 9q34. Adult-onset HSAN with anosmia (608720) may be another distinct form of HSAN, and HSAN1B (608088) with cough and gastroesophageal reflux maps to chromosome 3p24-p22.  http://www.omim.org/entry/162400
