Hereditary spastic paraplegia
Gene: ATP13A2Comment on mode of inheritance: Biallelic MOI supported by PMID:28137957 and OMIM.Created: 8 Jan 2019, 12:06 p.m.
Comment on list classification: Updating rating from Red to Green based on literature evidence. ATP13A2 was added to panel and rated Red by Chris Buxton (Bristol NHS) although he provides evidence of 3 unrelated cases in PMID:28137957. PMID:27217339 (Kara et al 2016) provides evidence of an additional case. Therefore sufficient (4) unrelated cases to support diagnostic rating, and ATP13A2 is associated with Spastic paraplegia 78, autosomal recessive, 617225 in OMIM.Created: 8 Jan 2019, 12:06 p.m.
In a 46-year-old man (proband 41), born of consanguineous Pakistani parents, with AR spastic paraplegia, Kara et al. (2016, PMID:27217339) identified a homozygous 3-bp deletion (c.3020_3022del, NM_001141974.2), resulting in an in-frame deletion (Phe1007del).Created: 8 Jan 2019, 12:05 p.m.
Estrada-Cuzcano (2017, 28137957) examined a Bulgarian family with 3 siblings affected by complicated hereditary spastic paraplegia, and identified a homozygous p.Thr512Ile (c.1535C>T) variant in ATP13A2. Further analysis of 795 index cases with HSP and related disorders revealed 2 additional families carrying truncating biallelic variants in ATP13A2. They also provide biochemical evidence that disease-causing variants can affect the catalytic autophosphorylation activity of ATP13A2.Created: 8 Jan 2019, 12:05 p.m.

Estrada-Cuzcano (2017, 28137957). Biallelic LoF varaints cause complicated hereditary spastic paraplegia.
Exome study identified biallelic missense . Further analysis of 795 HSP /erlated disorders identified 2 families with truncating ATP13A2 variants. Some supportive functional studies.
