Hereditary spastic paraplegia
Gene: ERLIN1Comment on list classification: Updated rating from Amber to Green after clinical advice from Helen Brittain, who notes that "the phenotype is certainly appropriate, it meets our guidance on number of unrelated families and >1 variant therefore it seems appropriate for a green rating. Re the nomenclature: (6-bp deletion, c.862_868delACCAGG) c.862_868del would usually indicate that 862-868 inclusive is deleted which would be 7bp... However they then wrote 6 nucleotides afterwards. If it is 6bp deleted it could be in frame (they have indicated deletion YQ) so I am not sure. On balance I think it is worth including."Created: 14 Jan 2019, 9:43 a.m.
Comment on list classification: Updated rating from Green to Amber awaiting further clinical review. A note of caution: OMIM states that in the article by Novarino et al. (2014), the nomenclature for the mutation in family 1598 was inconsistent, i.e., a 6-bp deletion, c.862_868delACCAGG.Created: 8 Jan 2019, 4:45 p.m.
Comment on list classification: Updated rating from Red to Green based on expert review and literature evidence. Gene added to panel and rated green by Alistair Pagnamenta (University of Oxford) based on PMID:24482476 which identified 7 HSP individuals from 3 families with homozygous variants in ERLIN1. Full phenotypes of affected individuals are supplied in the supplementary material.Created: 8 Jan 2019, 2:16 p.m.
PMID:24482476 (Novarino et al 2014) identified 18 previously unknown putative HSP genes. 7 individuals from 3 families (Family 786, 1098 and 1598) had homozygous variants in ERLIN1: c.C763T/p. R255X, c.G149T/p.G50V and c.862_868delACCAGG/p.del203-204YQ.Created: 8 Jan 2019, 2:12 p.m.

Novarino et al (2014) reported 7 affected individuals from 3 different consanguineous families had homozygous variants in this gene co-segregating consistent with an AR mode of inheritance. In the first of these families, significant evidence for genetic linkage was identified on 10q (pLOD >3.0) and this region harboured p.R255X (see PMID: 24482476)Created: 22 Nov 2018, 2:53 p.m.
