For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Experimental studies have shown that this premature translational stop signal affects ATP1A2 function (PMID: 24921013). ClinVar contains an entry for this variant (Variation ID: 692197). This premature translational stop signal has been observed in individual(s) with familial hemiplegic migraine (PMID: 18644608). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr1009*) in the ATP1A2 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 12 amino acid(s) of the ATP1A2 protein.
