BACKGROUND Genetic factors are the main cause of early miscarriage. This study aimed to investigate aneuploidy in spontaneous abortion by fluorescence in situ hybridization (FISH) using probes for 13, 16, 18, 21, 22, X and Y chromosomes. METHODS A total of 840 chorionic samples from spontaneous abortion were collected and examined by FISH. We analyzed the incidence and type of abnormal cases ...
Partial trisomy 8q is rare and has distinctive clinical features, including severe mental retardation, growth impairment, dysmorphic facial appearances, cleft palate, congenital heart disease, and urogenital anomalies. Partial monosomy 13q is a rare genetic disorder displaying a variety of phenotypic characteristics including mental retardation, dysmorphic facial features, and congenital anomal...
Although trisomy 16 is well recognised in spontaneous abortuses, it is infrequent in livebirths and there is little information about the clinical effects. We report two sibs with partial trisomy 16q resulting in infant death. Both children were severely growth retarded with small elfin faces, prominent foreheads, low set ears, abnormal external genitalia, and intractable diarrhoea.
Partial monosomy 10q25.2----qter, detected in a newborn baby with multiple congenital abnormalities, was found to be derived from a balanced maternal translocation t(6;10)(q27;q25.2). The pedigree of six generations of the family is presented. In an extensive cytogenetic study of this family, the chromosome complements of 57 subjects, potentially capable of carrying some form of this translocat...
A cytogenetic study of 15 triploid spontaneous abortuses, 12 trisomic abortuses, and their parents was carried out using the Q-banding technique. Polymorphic regions in abortus chromosomes were compared to corresponding regions of parental chromosomes to determine the origin of the extra chromosomes. Using marker chromosomes it was found that 7 triploids and only one trisomy were informative. T...
Partial trisomy 9 is a common autosomal trisomy, which is characterized by non-specific psychomotor delay, mental retardation and moderately abnormal characteristic facial features. Generally, partial trisomy 9 leads to variable phenotypes depending on the size and position of the duplicated region. However, a precise genotype/phenotype map has not been determined. The present study reports the...
