Novel splice-site variant of UCHL1 in an Indian family with autosomal recessive spastic paraplegia-79

Spastic Paraplegia-79 (SPG79) is an autosomal recessive type of childhood onset complicated by hereditary spastic paraplegia. SPG79 is characterized by spasticity, paraplegia, optic atrophy, cerebellar signs, and other variable clinical features. Recessive, disease causing variants in Ubiquitin C-te...

Zusammenfassung:Spastic Paraplegia-79 (SPG79) is an autosomal recessive type of childhood onset complicated by hereditary spastic paraplegia. SPG79 is characterized by spasticity, paraplegia, optic atrophy, cerebellar signs, and other variable clinical features. Recessive, disease causing variants in Ubiquitin C-terminal hydrolase-L1 (UCHL1) gene have been implicated as a cause for SPG79 in two families till now. In this study, we report on a third family of SPG79 with two similarly affected siblings, harboring a novel homozygous splice-site variant in the UCHL1 gene (NM_004181.4: c.459+2T>C). The variant was identified by whole-exome sequencing and validated by Sanger sequencing in the family.
