Comet assay was done, which showed results comparable with normal males. In bothgirls’ inguinal gonads was present which was removed and hormonal therapy with estrogen was given to preventosteoporosis. Androgen insensitivity syndrome can be inherited as an X linked disorder as evidenced by previousstudies.testicular feminization syndromeAndrogen Receptor DeficiencyPrimary amennorrheaComet assayCAISFamilial CAISJournal ArticleIndiaAssistant Professor, Department of Anatomy, Pondicherry Institute of Medical Sciences, Kalapet, Pondicherry, India.Additional Professor and Head, Department of Anatomy, JIPMER, Pondicherry, India
