  • Dr. Boada's research focuses on the cognitive and genetic underpinnings and comorbidity among speech, language, and reading disorders, as well as neuropsychological outcomes in children with epilepsy, stroke, and SCA's. (kennedykrieger.org)
  • Disorders of gene dosage can significantly increase risk for psychopathology, but outcomes vary greatly amongst carriers of any given chromosomal aneuploidy or sub-chromosomal copy number variation (CNV). (biomedcentral.com)
  • Second, we study sex as a neurobiological variable that influences mental health outcomes in the general population. (nih.gov)
  • Although sex hormones play a key role in sex differences in susceptibility, severity, outcomes, and response to therapy of different diseases, sex chromosomes are also increasingly recognized as an important factor. (biomedcentral.com)
  • As a result of the extra Y chromosome, each cell has a total of 47 chromosomes instead of the usual 46. (medlineplus.gov)
  • Aneuploidy effects on human gene expression across three cell types. (nih.gov)

  • A numerical chromosome abnormality can cause each cell to have 45 or 47 chromosomes in each cell. (diaridelsestudiants.com)
  • How many chromosomes does a trisomic cell have? (diaridelsestudiants.com)
  • genetics) Having three copies of a given chromosome in each somatic cell instead of the usual number of two. (diaridelsestudiants.com)
  • having a single extra chromosome in the cell in addition to the normal diploid number. (diaridelsestudiants.com)
  • This condition involves a cell with an incorrect number of chromosomes-too many or too few. (kentuckyfertility.com)
  • It's during this step that each half of the cell has an exact copy of the genetic information, thereby ensuring that each new cell has a complete set of chromosomes. (biologyideas.com)
  • One such error is 'non-disjunction', where chromosomes fail to separate and are pulled to the same side of the cell, leading to one cell having too many chromosomes and the other having too few. (biologyideas.com)
