Description

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1442501). This variant has not been reported in the literature in individuals affected with IMPDH1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change creates a premature translational stop signal (p.Gln350*) in the IMPDH1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in IMPDH1 are known to be pathogenic (PMID: 14981049, 33090715).
