PDE6C

PDE6C

A gene on chromosome 10q24 that encodes the alpha-prime subunit of cone phosphodiesterase, which is expressed in retinal cones.

Molecular pathology
PDE6C mutations are linked to cone dystrophy type 4.

A type of achromatopsia previously identified as ACHM1 was later found to be the same as ACHM3 caused by cyclic nucleotide-gated channel beta-3 (CNGB3) gene (MIM 605080).8 Among other genes are included cyclic nucleotide-gated channel alpha-3 (CNGA3; MIM 600053) causing ACHM29, Guanine nucleotide-binding protein G subunit [alpha]-2 (GNAT2; MIM 139340) causing ACHM4, 10 phosphodiesterase 6C (PDE6C; MIM 613093) causing ACHM5, 11 cone inhibitory phosphodiesterase 6H (PDE6H; MIM 601190) causing ACHM612 and activating transcription factor 6 (ATF6; MIM 605537) causing ACHM7.13 The current study was planned to report two Pakistani families that were initially evaluated as having nystagmus phenotype.
Homozygosity mapping reveals PDE6C mutations in patients with early-onset cone photoreceptor disorders.
Moreover, C3-knockout mice demonstrated higher expression levels of genes involved in maintaining the physiological function of the neural retina: abhydrolase domain containing 14A (Abhd14a); complexin 4 (Cplx4); cGMP specific-phosphodiesterase 6C (Pde6c); neurofilament (Nefl); aldehyde dehydrogenase family 1, subfamily A1 (Aldh1a1); retinitis pigmentosa GTPase regulator interacting protein-1 (Rpgrip1); and regulator of G protein signaling 9 binding protein (Rgs9bp).
These processes are represented in our study by several upregulated genes: Gucy2f, Ppt1, Bbs2, Crb1, Gabrr2, Rgs9bp, Rpgrip1, and Pde6c, which are essential for photoreceptor-based light-dependent signal transformation and transduction.
Phosphodiesterase 6C, encoded by our predicted gene PDE6C, has been confirmed to contribute to pyrimidine metabolism and phototransduction [129, 130].
