Comment on mode of inheritance: OMIM does indicate that it is X-linked recessive (biallelic in females), however two reviewers have indicated that monoallelic mutations in females can cause the disorder, and as this is the default X-linked setting this will be retained.

Comment on list classification: 5 reviewers agree.
