[Cytogenetic, molecular cytogenetic, clinical and genealogical study of mothers of children with autism: a search for family genetic markers of autistic disorders].
Using modern cytogenetic and molecular cytogenetic techniques towards the study of human chromosomes, an analysis of chromosomal abnormalities/chromosomal variations as well as clinical and genealogical data in mothers of children with autism has been performed. It has been shown that mothers of autistic children exhibit an increased incidence of chromosomal abnormalities (mainly mosaic forms involving chromosome X) and an increased occurrence of chromosomal variations compared to controls. The analysis of genotype-phenotype correlations revealed the increase in the frequency of cognitive disturbances and spontaneous abortions in mothers of children with autism as well as the higher frequency of mental retardation, early death and reproductive problems in the pedigrees. The high frequency of congenital malformations in the pedigrees of mothers with chromosomal variations was observed as well. Taking into account the data obtained, we have concluded that cytogenetic and molecular cytogenetic studies of mothers of children with autism are obligatory for detection of possible genetic causes of autism and genetic counseling of families with children affected with autistic disorders.
