Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PS1_Very_Strong PM2 PM5

The NM_001385079.1(PDE10A):​c.1800T>A​(p.Phe600Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Pathogenic in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F600C) has been classified as Likely pathogenic.

Genes affected

PDE10A (HGNC:8772): (phosphodiesterase 10A) The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase family. It plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This protein can hydrolyze both cAMP and cGMP to the corresponding nucleoside 5' monophosphate, but has higher affinity for cAMP, and is more efficient with cAMP as substrate. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Dec 2011]
