Table 3 Genotypes at the RET locus in Hadad and congenital central hypoventilation syndrome.
Haplotypes | Haddad | CCHS | Odds ratios |
---|---|---|---|
(n = 44) | (n = 99) | ||
ATA/ATA | 7 | 6 | 4.74 |
ATA/ATG | |||
ATA/GCG | 21 | 28 | 2.39 |
GCG/GCG | 16 | 65 | 1 |
ATA is the hypomorphic, HSCR predisposing RET haplotype and GCG the protective RET haplotype.
CCHS, congenital central hypoventilation syndrome; HSCR, Hirschsprung's disease.
