Hereditary spastic paraplegia
Gene: DSTYK
Gene to be reviewed again after the GMS Neurology specialist test group have reviewed and agreed rating of gene on the Hereditary spastic paraplegia - childhood onset panel on May 2019Created: 3 May 2019, 8:27 a.m.
Added 'Founder effect' tag based on haplotype analysis in Lee et al. (2017, PMID:28157540) which indicates a founder effect- the same deletion/insertion was identified in 3 unrelated families. At the time of curation, PMID:28157540 provides all evidence for the disease:gene association.Created: 11 May 2017, 9:59 a.m.
In affected members of 3 unrelated families of Middle Eastern descent with spastic paraplegia-23 (MIM:270750) Lee et al. (2017, PMID:28157540) identified a homozygous intragenic deletion/insertion in the DSTYK gene. The deletion segregated with the disorder in all 3 families. Haplotype analysis indicated a founder effect. The deletion insertion consisted of a 4-kb deletion associated with a 20-bp insertion, resulting in the removal of the last 2 exons of DSTYK (exons 12 and 13) along with part of the 3-prime untranslated region.Created: 11 May 2017, 9:58 a.m.
