Comment on mode of inheritance: Changed MOI due to upload of review MOI "X-LINKED recessive: hemizygous mutation in males, biallelic mutations in females" in inclusion of 'recessive' would result in an error with tiering, so has been corrected to 'X-LINKED: hemizygous mutation in males, biallelic mutations in females'
