Genes affected

PDE6G (HGNC:8789): (phosphodiesterase 6G) This gene encodes the gamma subunit of cyclic GMP-phosphodiesterase, which is composed of alpha- and beta- catalytic subunits and two identical, inhibitory gamma subunits. This gene is expressed in rod photoreceptors and functions in the phototransduction signaling cascade. It is also expressed in a variety of other tissues, and has been shown to regulate the c-Src protein kinase and G-protein-coupled receptor kinase 2. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2009]

The c.245C>T (p.A82V) alteration is located in exon 4 (coding exon 3) of the PDE6G gene. This alteration results from a C to T substitution at nucleotide position 245, causing the alanine (A) at amino acid position 82 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
