The frequency of carriers of X linked hypohidrotic ectodermal dysplasia among females with hypodontia of the permanent dentition (excluding third molars) could be as high as 1 in 500, and among females with deciduous hypodontia could be as high as 1 in 50. Since it may be possible to identify carriers form among female hypodontia cases in general by virtue of a reduced sweat pore count, the potential exists for a reasonably practical method of screening for carriers at the population level.
在恒牙列(不包括第三磨牙)出现缺牙的女性中,X连锁少汗型外胚层发育不良携带者的频率可能高达五百分之一,而在乳牙列出现缺牙的女性中,这一频率可能高达五十分之一。由于一般而言,通过减少汗孔计数有可能在女性缺牙病例中识别出携带者,因此存在一种在人群层面进行携带者筛查的合理实用方法。
