What are the different types of structural chromosomal aberrations seen in karyograms? 


Best insight from top research papers

Structural chromosomal aberrations seen in karyograms include deletions, duplications, inversions, and translocations . Deletions refer to missing segments of chromosomes, which can be lethal in homozygous state and can uncover recessive genes in heterozygous state. Duplications cause an imbalance in genetic material and can lead to increased gene function variety. Inversions occur when a segment of a chromosome turns 180 degrees, causing pairing difficulties during meiosis and resulting in inviable products from crossing over within inversion loops. Translocations involve the relocation of a chromosomal segment to another position in the genome, leading to unbalanced zygotes and new gene linkages. Chromosome rearrangements can cause ill health in humans, including infertility and mental retardation .

What are the most common genetic disorders associated with a normal karyotype as identified through next-generation sequencing (NGS)?5 answersNext-generation sequencing (NGS) studies have identified several common genetic disorders associated with a normal karyotype in acute myeloid leukemia (AML) patients. Mutations in genes like NPM1, DNMT3A, FLT3-ITD, IDH1, PTPN11, and RAD21 are frequently observed. Additionally, somatic mutations in genes linked to histone modification and signaling pathways, such as CEBPA, RUNX1, and ASXL1, are significantly associated with an increased risk of progression to AML in patients with cytogenetically-normal MDS. Furthermore, the presence of copy number alterations (CCA) in up to 50% of de novo NK-AML patients has been reported, impacting patient outcomes negatively. These findings underscore the importance of comprehensive molecular profiling in identifying genetic lesions and guiding treatment strategies for patients with normal karyotype-associated genetic disorders.
What is the differnce between chromatid and chromosome?5 answersChromatids are the two identical copies of a chromosome that are created during DNA replication and are held together at the centromere until they separate during cell division. On the other hand, a chromosome is a single DNA molecule wrapped around proteins, forming a condensed structure that contains genetic information. Chromosomes play a crucial role in storing and organizing genetic material within the nucleus of eukaryotic cells, while chromatids are specifically involved in the process of cell division, ensuring accurate distribution of genetic material to daughter cells. Understanding the distinction between chromatids and chromosomes is essential in comprehending the mechanisms of DNA replication, cell division, and genetic inheritance. Both chromatids and chromosomes are integral components of the complex chromatin structure that regulates gene expression and cellular processes.
What are the cytogenetic abnormalities in myelodysplastic syndrome?4 answersMyelodysplastic syndrome (MDS) is characterized by cytogenetic abnormalities, including chromosomal deletions, trisomies, inversions, and complex karyotypes. Common cytogenetic abnormalities in MDS include del(5q), -7/del(7q), +8, and -Y. Other less common abnormalities include -X, 3q abnormalities, +13/del(13q), i(17q), and +21/-21. In pediatric MDS patients, clonal chromosome abnormalities such as monosomy 7, trisomy 8, inv(17)(p11.2q21), and complex karyotypes have been observed. Additionally, submicroscopic aberrations such as p53 deletions have been detected in pediatric MDS patients, particularly in cases of hypocellular refractory cytopenia of childhood (RCC). Chromosome 5 and 7 abnormalities are common genetic abnormalities in MDS patients and are used to identify prognosis risk groups and guide treatment decisions. The presence of clonal cytogenetic abnormalities, except for +8, del(20q), and -Y, can serve as presumptive evidence of MDS in patients with cytopenia(s).
What are the different types of chromatin remodeling?5 answersChromatin remodeling is performed by two major types of complexes: covalent histone- or DNA-modifying complexes and ATP-dependent chromosome remodeling complexes. The ATP-dependent chromatin remodeling complexes are further classified into four subfamilies: SWI/SNF, CHD, INO80/SWR, and ISWI. The SWI/SNF subfamily remodelers evict or displace nucleosomes from chromatin, promoting recruitment of transcription machinery and DNA repair factors. The CHD and ISWI subfamily remodelers slide nucleosomes and arrange them in a regularly spaced array. The INO80 subfamily remodelers escort nucleosome organization and editing. These chromatin remodeling complexes play crucial roles in regulating gene expression, transcription, DNA repair, and chromatin accessibility. They are targeted to specific chromatin regions by transcription factors and non-coding RNA to remodel the chromatin into functional states. The different types of chromatin remodeling complexes have distinct preferences for binding at actively marked or repressively marked chromatin.
What is the significance of cytogenetic abnormalities in the prognosis of AML?5 answersCytogenetic abnormalities play a significant role in the prognosis of acute myeloid leukemia (AML). These abnormalities, which involve changes in the structure or number of chromosomes, can provide important prognostic information and help guide treatment decisions. In some cases, specific cytogenetic abnormalities are associated with a more favorable prognosis, such as NPM1 mutations in AML. On the other hand, certain abnormalities, such as -5, -16, -18, del(11)(p15.1p15.4), del(13)(q12.11q22.3), and +8, have been found to be associated with poorer overall survival in AML patients. Additionally, the presence of cytogenetic abnormalities at the time of relapse has been shown to be an independent risk factor for survival in pediatric relapsed AML. Therefore, cytogenetic analysis is crucial in AML to classify prognostic groups, guide treatment strategies, and improve patient outcomes.
What are the different types of chromosomal mutations?3 answersChromosomal mutations can be classified into two types: constitutional chromosomal anomalies that arise in germ cells and contribute to inherited diseases, and acquired chromosomal mutations that occur in somatic cells and contribute to acquired diseases. Constitutional chromosomal anomalies can result from mutations involving alterations in chromosome number, which have an age-dependent mutation rate. Acquired chromosomal mutations can be generated through mechanisms such as non-homologous end joining (NHEJ) or replication-based mechanisms like microhomology-mediated break-induced replication (MMBIR). Chromosomal mutations can lead to complex genomic rearrangements, including duplications, triplications, and rearrangements involving multiple genes. These mutations are distinct from gene mutations, which involve single genes and can be subject to modification.
