While consulting the Exome Aggregation Consortium Database (ExAC) I noticed that the identified variant at position chrX:153,173,202 has a frequency of >1% in the East Asian population (see http://exac.broadinstitute.org/variant/X-153173202-G-A). This frequency may be too high to fully explain the clinical phenotype in this family. Furthermore, the variant is referred to as "T491M" in the Abstract, but is "T941M" in the rest of the manuscript.
