MULTIPLE CONGENITAL ANOMALIES IN A CHILD WITH 47,XY,+der(8;9)(p10;p10): A CASE REPORT
Abstract:
Complex small supernumerary marker chromosomes (sSMC) constitute one of the smallest subgroups of sSMC in general. Complex sSMC consist of chromosomal material derived from more than one chromosome. We report a complex sSMC derived from chromosomes 9 and 8, characterized as der(8;9)(p10;p10) resulting from unbalanced transition of maternal balanced translocation. Besides dysmorphic face and mental-motor retardation, the patient had Dandy-Walker malformation (DWM) in cranial MR also. As far as we are concerned, this is the first complex sSMC case comprising short arms of 8th and 9th chromosomes.

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Nondisjunction
5.8K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

Nondisjunction

During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
