Genes affected
CDHR1 (HGNC:14550): (cadherin related family member 1) This gene belongs to the cadherin superfamily of calcium-dependent cell adhesion molecules. The encoded protein is a photoreceptor-specific cadherin that plays a role in outer segment disc morphogenesis. Mutations in this gene are associated with inherited retinal dystrophies. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2013]

Collection Method: clinical testing

The c.1133G>A (p.R378Q) alteration is located in exon 11 (coding exon 11) of the CDHR1 gene. This alteration results from a G to A substitution at nucleotide position 1133, causing the arginine (R) at amino acid position 378 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
