Description

This sequence change creates a premature translational stop signal (p.Arg279*) in the ASS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ASS1 are known to be pathogenic (PMID: 18473344, 19006241). This variant is present in population databases (rs121908645, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with citrullinemia type 1 (PMID: 11571557, 16475226, 27287393, 28111830). ClinVar contains an entry for this variant (Variation ID: 6333). For these reasons, this variant has been classified as Pathogenic.
