Green List (high evidence)

Pre-print (https://sciprofiles.com/publication/view/62eb776390415f0166f73fae7cd172ed)

Review of research and diagnostic databases and literature review found 50 individuals from 31 families with biallelic variants.

13 PTCS (including splice) and 15 missense resulting in gain or loss of Cys residue.

AR PTCs are associated with early onset leukoencephalopathy including cognitive decline, dev delay/ID and dysmorphism; seizures, spasticity, hypotonia, ataxia

AR missense are associated with CADASIL-like phenotype
