A rare family with Hereditary Spastic Paraplegia Type 35 due to novel FA2H mutations: a case report with literature review.

BackgroundHereditary Spastic Paraplegia Type 35 is a complicated form of HSP characterized by progressive spastic paraparesis, dysarthria, and mild cognitive decline associated with leukodystrophy on brain imaging. Mutations in the fatty acid 2-hydroxylase (FA2H) gene have been associated SPG35.MethodsSequencing of FA2H gene was conducted in a Chinese non- consanguineous family with two affected siblings manifesting with typical clinical features of SPG 35. 100 healthy individuals were set for control.ResultTriple heterozygous mutations in FA2H gene (c.968C>A; c.976G>A; c.688G>A) were identified in the two affected siblings. All the mutations were not documented previously and were not detected among 100 healthy controls.ConclusionIn this study we identified the first SPG 35 family in Han population. Triple FA2H mutations seem to result in a severe phenotype while more patients are needed to establish the genotype-phenotype correlations.
