  • Abstract
  • Look Inside

We analyzed the DNA for visual pigment genes in 38 mothers whose sons had congenital colorvision deficiencies and in 104 randomly selected females. Polymerase chain reaction (PCR) was used to separately amplify the most upstream genes, downstream genes and the most downstream genes in the red-green pigment gene arrays. Exon 5 of each gene was analyzed by single-strand comformation polymorphisms (SSCP). Abnormal patterns were detected in 14 randomly selected females (13%) , of whom 5 appeared to be protan carriers and 9 to be deutan carriers. Since the incidence of females showing abnormal patterns was slightly higher than expected, some false-positive cases may be present in these 14 cases.
