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]

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.001 (152/151866) while in subpopulation AFR AF = 0.00355 (147/41388). AF 95% confidence interval is 0.00308. There are 1 homozygotes in GnomAd4. There are 84 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
