Description

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in PSAT1 are known to be pathogenic (PMID: 17436247, 25152457). This variant has not been reported in the literature in individuals with PSAT1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Val60Cysfs*5) in the PSAT1 gene. It is expected to result in an absent or disrupted protein product.
