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

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. Scorers claiming Benign: max_spliceai.
• PP5: Variant 6-165450242-C-G is Pathogenic according to our data. Variant chr6-165450242-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 225634.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr6-165450242-C-G is described in Lovd as [Pathogenic].
