21-hydroxylase<unk>  is<unk>  by mutations in CYP21A1 and CYP21A2 genes found on chromosome 6. Approximately 70% of CYP21A2 disease is due to gene conversion and microdeletions in CYP21A1 gene; around 25% to 30% are chimeric genes due to large deletions. Less common<unk>  are due to de novo mutations because of high variability of the CYP21A2 locus. Also, chromosome 6 uniparental disomy is rare<unk> of 21-hydroxylase<unk>  with an unknown prevalence.
