Genes affected

PDE8B (HGNC:8794): (phosphodiesterase 8B) The protein encoded by this gene is a cyclic nucleotide phosphodiesterase (PDE) that catalyzes the hydrolysis of the second messenger cAMP. The encoded protein, which does not hydrolyze cGMP, is resistant to several PDE inhibitors. Defects in this gene are a cause of autosomal dominant striatal degeneration (ADSD). Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2010]

WDR41 (HGNC:25601): (WD repeat domain 41) Contributes to guanyl-nucleotide exchange factor activity. Involved in regulation of autophagy. Located in cytoplasm. Part of guanyl-nucleotide exchange factor complex. Colocalizes with Atg1/ULK1 kinase complex. [provided by Alliance of Genome Resources, Apr 2022]
