Introduction: Down syndrome as a genetic disorder is a popular research topic in molecular studies. One way to study Down syndrome is via bioinformatics.  Methods: In this study, a gene expression profile from a microarray study was selected for more investigation. Results: The study of Down syndrome patients shows specific genes with differential expression and network centrality properties....

down syndrome is the most common known chromosomal disorder in man.this syndrome has many sings and symptoms which are variable in frequency.taking all the signs and symproms in to consideration,diagnosis of down syndrome is not a difficult task-however in the past it was difficult to diagnose this syndrome based on a single clinical sign,until  hypertrophy of hyponichium was first introduced b...

disorder in re-methylation process of homocysteine to methionine due to mutation in betaine homocysteine methyltransferase enzyme (bhmt) coding gene, leads to decrease in s-adenosyl methionine (sam) synthesis which takes part in dna methylation as a methyl donor. as a result, it can promote hypo-methylation of dna, chromosome instability, and chromosome missegregation, which in turn is one of t...

down syndrome (ds), trisomy 21, is the most common chromosomal syndrome that affects one in 600-800 live births. the advanced maternal age is the only well known risk factor to cause ds. our study revealed that many young mothers produced ds children than advanced age mothers in india. a total of 150 suspected ds cases were investigated cytogenetically. randomly selected 200 healthy families in...

the purpose of the present study is the comparison of the pattern of language perception in down syndrome (ds) children and typical children. to achieve the objective, nine subjects with ds (whose mental ages were 72-78 months and were drawn from five center of special education in the city of mashhad) and five typical children with the same mental ages were selected through random sampling; an...
