Familial occurrence of unilateral giant breasts in Nigeria: a possible new genetic entity.

abstract：BACKGROUND:Retinitis pigmentosa (RP) is the most common form of inherited retinal dystrophy, with a worldwide prevalence of 1 in 4000 persons. While in most cases of RP, the disease is limited to the eye (non-syndromic), over 40 forms of syndromic RP have been described. OBJECTIVES:To identify the genetic basis for sy...
