X-linked progressive cone dystrophy (XLPCD) is characterized by progre
ssive macular atrophy, abnormal colour vision, reduced cone responses
in ERG, and reduced visual acuity. XLPCD may be genetically heterogene
ous. Therefore, carrier detections by DNA analysis may only be carried
out in those families in which the position of the gene locus can be
clearly established. Here, we describe the first DNA carrier detection
s in XLPCD.
