The c.738C>T variant in the PDHA1 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The c.738C>T variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Multiple in silico algorithms predict that c.738C>T may create a cryptic donor site upstream of the natural donor site of intron 7. However, in the absence of RNA/functional studies, the actual effect of c.738C>T is unknown. The c.738C>T variant is a strong candidate for a pathogenic variant. However, the possibility it may be a rare benign variant cannot be excluded.
