Hereditary spastic paraplegia - childhood onsetGene: PCYT2
Comment on list classification: Changed rating to Amber so that Green genes on this panel reflect the NHS signed-off version. This will be reviewed at the next GMS panel update.

Panel Version: 2.19
Comment on list classification: Added to panel based on sufficient cases in PMID:31637422 with HSP phenotype. Updated rating to Green following confirmation from Helen Brittain, Genomics England Clinical Team, that phenotype is appropriate for the panel. Added 'for-review' tag so that GLHs can confirm that gene is indeed required for childhood onset panel (as Helen notes: one patient had onset at 16 and mild delay of motor skills).

Panel Version: 2.12
PMID:31637422. In 5 patients from 4 unrelated families with autosomal recessive spastic paraplegia-82 (MIM:618770), Vaz et al. (2019) identified homozygous or compound heterozygous mutations in the PCYT2 gene. The variants segregated with the disorder in all families. Functional studies showed reduced (not absent) PYCT2 activity.
