Table 1. Frequencies of shorter (≤ 18 repeats) and longer (≥ 26 repeats) CAG alleles between pediatric and adolescent/ adult groups according to CYP21A2 genotypes.

	A/C genotype group			C/C genotype group
	Age group	CYP21A2 genotype	Allelic frequency (%)	Age group	CYP21A2 genotype	Allelic frequency (%)
Longer alleles	Pediatric	A/C	13	Pediatric	C/C	16
	Adolescent/ adult	A/C	18 p = 0.5	Adolescent/ adult	C/C	9 p = 0.28
Shorter alleles	Pediatric	A/C	10	Pediatric	C/C	2
	Adolescent/ adult	A/C	15 p = 0.37	Adolescent/ adult	C/C	17 p = 0.01
