This CNV region is reported to have variations of one, two, three or four repeats. Telomeric end is STK19 gene and centromeric end is TNXB gene. Within repeat sequence, C4 and CYP21 are multiplicated as complete genes, whereas STK19 and TNX were truncated to become pseudogenes, STK19P and TNXA, respectively. SNP rs3130342 is located at 5’-UTR of TNXB gene and is not included in the repeat sequence. b There are four major variants of C4 genes. Left figure shows that C4 long gene has insertion sequence named HERV-K(C4) in intron 9, whereas C4 short gene does not. C4A and C4B variants differ by only 4 amino acids at position 1101-1106, as shown in right figure.
