RCV001344526 | SCV001538586 | uncertain significance | Multiple gastrointestinal atresias | 2020-09-24 | criteria provided, single submitter | clinical testing | This sequence change results in a premature translational stop signal in the TTC7A gene (p.Gln828*). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 31 amino acids of the TTC7A protein. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with gastrointestinal defects and immunodeficiency syndrome (PMID: 24931897). This variant disrupts a region of the protein in which other variant(s) (p.Ala832Thr, p.Ala839Thr) have been observed in individuals with TTC7A-related conditions (PMID: 24417819, 29174094). This suggests that this may be a clinically significant region of the TTC7A protein. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
