[Characteristics of congenital morphogenetic variants in hygienic studies].
The study was undertaken to examine the basic frequencies of congenital morphogenetic variants (CMVs) among preschool children. The basic frequencies were valid if the population frequency was more than 2-4 %. The least valid frequencies were characteristic of rare signs at a frequency of less than 1%. It is suggested that rare signs be integrated into an individual group and then their average be compared.
