Comment on list classification: Sufficient evidence to promote this gene to Green at the next GMS panel update (added 'for-review' tag) - sufficient number of unrelated cases with relevant phenotype, supported by functional data.Created: 22 Jan 2021, 5:07 p.m. | Last Modified: 22 Jan 2021, 5:07 p.m.

Currently not associated with any phenotype in OMIM (last edited on: 10/07/2001) but has a 'probable' gene rating for 'PPIL1-related Neurodegenerative Pontocerebellar Hypoplasia with Microcephaly' in Gene2Phenotype.
- PMID: 33220177 (2021) - At least 12 variants identified in 17 individuals from 9 unrelated families. All displayed pontocerebellar hypoplasia and progressive congenital microcephaly (-4 to -8 SD HC). Further common phenotypes included hypotonia, seizures, intellectual disability with delayed language and motor development, and cortical changes on brain MRI, most notably simplified gyri pattern. Pathogenicity is supported by mouse model.
