Genes affected

PDC (HGNC:8759): (phosducin) This gene encodes a phosphoprotein, which is located in the outer and inner segments of the rod cells in the retina. This protein may participate in the regulation of visual phototransduction or in the integration of photoreceptor metabolism. It modulates the phototransduction cascade by interacting with the beta and gamma subunits of the retinal G-protein transducin. This gene is a potential candidate gene for retinitis pigmentosa and Usher syndrome type II. Alternatively spliced transcript variants encoding different isoforms have been identified.

Ambry Genetics

Nov 21, 2022

The c.724G>C (p.E242Q) alteration is located in exon 4 (coding exon 3) of the PDC gene. This alteration results from a G to C substitution at nucleotide position 724, causing the glutamic acid (E) at amino acid position 242 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
