Description

For these reasons, this variant has been classified as Pathogenic. This premature translational stop signal has been observed in individual(s) with clinical features of TYR-related conditions (PMID: 26785811, 31077556). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Trp218*) in the TYR gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TYR are known to be pathogenic (PMID: 23504663).
