Hereditary spastic paraplegia v1.157 | CYP27A1 | Rebecca Foulger Added comment: Comment on list classification: Updated rating from Red to Amber awaiting further clinical review. CYP27A1 was added to panel and rated Amber by Chris Buxton (Bristol NHS). Multiple cases from literature of spastic paresis presenting with Cerebrotendinous xanthomatosis (CTX), which is caused by variants in CYP27A1. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Hereditary spastic paraplegia v1.155 | CYP27A1 | Rebecca Foulger commented on gene: CYP27A1: PMID:29321515 (Sekijima et al, 2018) conducted a Japanese survey on Cerebrotendinous xanthomatosis (CTX). The most common initial symptom was tendon xanthoma, followed next by spastic paraplegia, cognitive dysfunction, cataract, ataxia, and epilepsy. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Hereditary spastic paraplegia v1.155 | CYP27A1 | Rebecca Foulger commented on gene: CYP27A1: PMID:27455001 (Zhang et al 2017) report a 27 year old male with mental retardation and subsequently memory lapses, ataxia, spastic paraplegia and fuzzy language. The patient was found to have a compound het variant in CYP27A1. The article is in Chinese, preventing further reading. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Hereditary spastic paraplegia v1.155 | CYP27A1 | Rebecca Foulger commented on gene: CYP27A1: PMID:28623566 (Chen et al 2017) investigated clinical symptoms of Chinese CTX patients. Three novel variants of p.Arg513Cys, c.1477-2A>C in family 1 and p.Arg188Stop in family 4 (NM 000784.3) in CYP27A1 were found. The probands in the study manifested cerebellar ataxia, tendon xanthoma and spastic paresis in family 1 and 4. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Hereditary spastic paraplegia v1.155 | CYP27A1 | Rebecca Foulger commented on gene: CYP27A1: PMID:26874936 (Rasafio et al 2016) report 2 Italian siblings from a consanguineous family with Cerebrotendinous xanthomatosis and different phenotypes but the same G-to-A transition causing splicing alteration. The 41 year old male presented with mutacism, spastic tetraparesis, bilateral pes cavus, sialorrhea, progressive dysphagia and head dystonia. Genetic testing of other family members revealed the same variant in a sister who had mild spastic paraparesis amongst her symptoms, and a status of asymptomatic carriers of heterozygous mutation in two sisters. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
