Clinical Features

Kamenarova et al. (2013) studied a 3-generation Romani family segregating autosomal dominant cone-rod dystrophy with a slightly variable but early age of onset, at around 10 years of age. Affected individuals had gradual visual impairment and photophobia; ophthalmoscopy revealed typical signs of CORD including narrowing of retinal vessels, scattered bone-spicule pigmentation in the midperipheral retina, retinal pigment epithelium atrophy, and optic disc pallor. Electroretinography showed reduced photopic and scotopic responses, and visual field examination demonstrated central scotoma.

Mapping

In a 3-generation Romani family segregating autosomal dominant cone-rod dystrophy (adCORD), in which known loci associated with adCORD had been excluded, Kamenarova et al. (2013) performed a genomewide analysis using short tandem repeat markers and obtained a maximum lod score of 3.31 for a 6.7-Mb region on chromosome 10q26 between markers D10S1757 and D10S1782. An independent genomewide scan using SNP microarray defined a 7.3-Mb region on 10q26, spanning the 6.7-Mb interval highlighted by the original STR markers.

Molecular Genetics

In a 3-generation Romani family segregating autosomal dominant cone-rod dystrophy (adCORD) mapping to chromosome 10q26, Kamenarova et al. (2013) screened key positional candidate genes but found no pathogenic variants, and high-density oligonucleotide-based array CGH revealed no chromosomal aberration, deletion, or amplification of a part of whole gene.
