AR and Turner syndrome: These include mutations on both X chromosomes, either homozygous or compound heterozygous ones [31], an isodisomy of the maternal X chromosome with a pathogenic variant in DMD [32], Turner syndrome in patients carrying a mutation on the single X chromosome [33], women with an XY karyotype carrying a mutation in DMD and a (nonsense) mutation in the androgen receptor (AR) on the X chromosome, resulting in the female phenotype [34], or translocations between the X chromosome and an autosome with the breakpoint in DMD [35].
