Indian Journal of Human Genetics. 1999 Jan; 5(1): 41-44.http://imsear.searo.who.int/handle/123456789/159876A study of 720 probands of vitiligo with positive family history indicated early mean age at onset for the female probands (19.68 + 17.76) as compared to male probands (25.43 + 13.87). The incidence of the condition among the biological relatives of the patients studied showed a prevalence rate of 7.31% which is considerably high from the prevalence of 0.95% of the condition observed in the population of our country. The risks estimated for different relatives of the proband indicated higher risk for progeny of the proband as compared to the sibs. The risk for the cousins of the probands was about two to three folds higher as compared to that in the offsprings and the sibs.enVitiligopopulation frequencyrisk estimateage at onsetArticle
