Green List (high evidence)

In addition to previous reports of Spastic paraplegia 79, autosomal recessive (OMIM:615491), PMID: 35986737 reports a neurodegenerative disorder with spasticity, ataxia, neuropathy, and optic atrophy in cases with heterozygous UCHL1 variants. The variants included 13 heterozygous loss-of-function variants (15 families) and a heterozygous in-frame insertion (3 families). The affected individuals mainly presented with spasticity (24/31), ataxia (28/31), neuropathy (11/21), and optic atrophy (9/17), it was also noted in PMID: 35986737 that the condition onset in dominant cases was median 49 years (12-70 years) and in recessive was 7.5 years (2-10 years).
