Allelic polymorphism of MTHFR, MTR and MTRR genes in patients with cleft lip and/or palate and their mothers
[Free Full Text (pdf)]
The frequency of common MTHFR, MTR and MTRR genes polymorphisms was evaluated among patients with non-syndromic cleft lip and/or palate (CL/P), their mothers and healthy persons from West-Ukrainian region. MTHFR 677TT genotype was shown to increase more than three-fold risk of CL/P and for mothers the risk of having CL/P children may increase two-fold compared with homozygous carriers of MTHFR 677ÑÑ genotype (OR = = 3.3, OR = 1.92, respectively). The heterozygous MTR 2756ÀG genotype was associated with 1.5-fold increased risk of CL/P compared with the AA genotype (OR = 1.48). The heterozygous genotype MTRR 66AG was associated with the 5.56-fold increased CL/P risk (OR = 5.56) and for mothers with 2.6-fold increased risk of delivering a CL/P offspring (OR = 2.6). The results showed that MTRR 66G allele is more prevalent than MTRR 66A (wild type) and the MTRR 66GG genotype frequency was significantly lower among CL/P patients and their mothers than in control group among Western Ukrainian inhabitants.
