Chromosome Deletion 1q43q44: A Case Review
Neonatal Network : NN
|August 31, 2019
Summary
A rare chromosome abnormality, 1q43q44 deletion, is discussed. This subtelomeric deletion on chromosome 1 can cause multiple anomalies in neonates, often diagnosed during NICU stays.
Area of Science:
- Medical Genetics
- Neonatal Care
Background:
- Chromosome abnormalities are frequently identified in Neonatal Intensive Care Units (NICUs).
- Prenatal diagnosis is not always available, necessitating diagnosis during the neonatal period.
- NICU providers require extensive knowledge of chromosomal disorders to guide families.
Observation:
- This case study focuses on a rare deletion on chromosome 1q43q44.
- This deletion occurs in the subtelomeric region of the long arm of chromosome 1.
- Baby D presented with multiple congenital anomalies.
Findings:
- Baby D was diagnosed with the 1q43q44 deletion.
- This condition involves a specific deletion pattern on chromosome 1.
- The case highlights the clinical presentation of this rare genetic disorder.
Implications:
- Accurate diagnosis of rare chromosome abnormalities is crucial in the NICU.
- Understanding such deletions aids in genetic counseling and family support.
- This case contributes to the literature on 1q43q44 deletions and their impact.

Polytene Chromosomes
10.9K
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...

Chromosome Structure
26.0K
A functional eukaryotic chromosome must contain three elements: a centromere, telomeres, and numerous origins of replication.
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
Telomeres consist of non-coding repetitive nucleotide...

Lampbrush Chromosomes

In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...

Chromosome Replication
10.5K
Before a cell can divide, it must accurately replicate all of its chromosomes, including the DNA and its associated histone and non-histone proteins. This process begins at numerous origins of replication during the S phase of the cell cycle in each of a cell’s chromosomes simultaneously. Certain nucleotides can act as origins of replication, but these sequences are not well defined - especially in complex, multi-cellular, eukaryotic species. The length of DNA that spans an origin...

Chromosomal Theory of Inheritance
59.7K
In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Review and Preview

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
