Likely pathogenic, criteria provided, single submitter	clinical testing	Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego	Sep 30, 2020	This variant is located in the promoter region of UFM1 and has been previously reported as a homozygous change in sixteen patients with hypomyelination with atrophy of the basal ganglia and cerebellum (PMID: 28931644). Most of the patients were from Roma population, and the carrier frequency was as high as 25% in Eastern Slovakia (PMID: 28931644), suggesting a founder effect. In-vitro functional studies using a luciferase assay showed that this variant leads to reduced promoter activity in CNS-derived cell lines (PMID: 28931644). It is absent from the gnomAD population database and thus is presumed to be rare. Based on the available evidence, the c.-273_-271delTCA variant is classified as Likely Pathogenic. -
