RESUMEN
OBJECTIVE: The aim: The article deals with analyzing the influence of polymorphic variants of CYP19A1 [rs2414096, rs936306], ESR1 [rs2234693, rs9340799], IL1 [rs1143627], IL6 [rs1800796], IL10 [rs1800896] and RANKL [rs959389] genes on deciduous tooth eruption terms in individuals born macrosomic. PATIENTS AND METHODS: Materials and methods: 171 individuals participated in the multi-stage study (144 macosomic-at-birth individuals and 27 normosomic-at-birth persons). This study included only persons who have preserved information about the timing of deciduous tooth eruption - 159 persons (aged from 4 to 55 years), male and female (male / female ratio was 1.5 / 1). RESULTS: Results and conclusions: The presence of the G allele in CYP19A1 [rs2414096] gene and the -351 A allele in ESR1 [rs9340799] gene were found to be risk factors for fetal macrosomia formation. The research revealed an association of RANKL [rs9594759] gene variants which is a multiplicative model of inheritance and IL-10 [rs1800896], an overdominant model of inheritance, with an increased risk of tooth delay. Besides the variants of RANKL [rs9594759] and IL-10 [rs1800896] genes a multidirectional modifying effect on the timing of tooth eruption in macrosomic-at-birth individuals made the variant of CYP19A1 [rs2414096] gene - a significant dominant and over-dominant model of inheritance. Further analysis of intergenic interactions will facilitate the application of the obtained results in clinical practice by creating a molecular profile of individuals with deviations in the tooth eruption timing.
