GeneDx	RCV000578985	SCV000681072	likely pathogenic	not provided	2017-11-02	criteria provided, single submitter	clinical testing	The R765X variant in the ALDH18A1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is predicted to cause loss of normal protein function through protein truncation. The R765X variant is not observed in large population cohorts (Lek et al., 2016). We interpret R765X as a likely pathogenic variant.

While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 31 amino acid(s) of the ALDH18A1 protein. This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with multiple congenital anomalies (PMID: 33144682). ClinVar contains an entry for this variant (Variation ID: 489087). 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.
