Description

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in MCOLN1 are known to be pathogenic (PMID: 11030752, 11317355). This variant has not been reported in the literature in individuals with MCOLN1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu242Serfs*18) in the MCOLN1 gene. It is expected to result in an absent or disrupted protein product.
