    Response to 'Female carriers'

    Dear Mr Instone - Many thanks for your interest in our work and your comment! In our analyses we did look at ICD-10 diagnoses of atrial fibrillation/flutter, and self-reported heart problems in female carriers versus female non-carriers, but didn't see any difference in prevalence between the two groups (results in the Supplementary Data). However, as these are relatively crude measures, we cannot the exclude the possibility that there are actually higher rates of subtle cardiac dysfunction in female carriers relative to non-carriers, and further, more focussed studies might look at this. Regards, Dr William Davies

    Female carriers

    Fascinated to see the comments about irregular heartbeats as an x-linked ichthyosis suffer myself. If you are carrying out further studies I wonder if there is any trend for female carriers having the same. My mother an x-linked ichthyosis carrier has always had an extra hearth beat that causes problems for medical exams and operations. Could it be used as an additional test for expectant mums for potential x-linked babies. A great article and thanks - Jeremy Instone
