Description

This sequence change creates a premature translational stop signal (p.Ser9*) in the TTPA gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TTPA are known to be pathogenic (PMID: 9463307, 26068213). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with TTPA-related conditions (PMID: 31069529). For these reasons, this variant has been classified as Pathogenic.
