Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

36.5K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Pleiotropy01:33

Pleiotropy

42.9K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Nondisjunction01:29

Nondisjunction

81.4K
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.

Nondisjunction01:21

Nondisjunction

4.6K
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...

Meiosis I01:49

Meiosis I

214.0K
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by...

    • Pediatric Orthopedics
    • Developmental Biology

    Background:

    • Arthrogryposis multiplex congenita (AMC) is a clinical descriptor for conditions with multiple congenital joint contractures.
    • It stems from decreased fetal movement in utero, with diverse underlying causes.
    • Causes can include maternal factors, nervous system pathology, or genetic abnormalities.

    Purpose of the Study:

    • To provide a comprehensive overview of Arthrogryposis multiplex congenita.
    • To highlight the importance of identifying the etiology of AMC.
    • To discuss diagnostic and therapeutic considerations.

    Main Methods:

    • Review of existing literature on Arthrogryposis multiplex congenita.
    • Synthesis of information regarding causes, diagnosis, and management.
    • Emphasis on the significance of etiological determination.

    Main Results:

    • AMC is characterized by joint contractures resulting from reduced fetal movement.
    • Prenatal diagnosis can be challenging, often requiring advanced imaging.
    • Postnatal care may involve respiratory and feeding support.
    • Physical therapy and surgery are key interventions for contractures.

    Conclusions:

    • Timely intervention improves outcomes for infants with AMC.
    • Syndromic forms of AMC are associated with poorer prognoses.
    • Determining the specific cause of AMC is vital for accurate prognosis and family counseling regarding recurrence risks.
