Summary
A rare deletion on chromosome 1p32.1p32.3 was identified in an 18-month-old girl with developmental delay and dysmorphic features. This specific genetic finding and its associated clinical presentation are previously unreported.
Area of Science:
- Genetics
- Developmental Pediatrics
- Clinical Dysmorphology
Background:
- Developmental delay and dysmorphic features are common presenting symptoms in pediatric genetics.
- Chromosomal abnormalities, including deletions, can lead to complex congenital conditions.
Observation:
- An 18-month-old female patient presented with global developmental delay and distinct dysmorphic features.
- Karyotyping revealed a specific deletion on chromosome 1, denoted as 46,XX,del(1)(p32.1p32.3).
Findings:
- The identified deletion, del(1)(p32.1p32.3), represents a novel chromosomal abnormality in terms of its association with clinical phenotype.
- This case highlights a unique genetic cause for the observed developmental and morphological abnormalities.
Implications:
- This report expands the known spectrum of clinical features associated with chromosome 1 deletions.
- Further research into this specific deletion may elucidate critical genes involved in neurodevelopment and morphogenesis.
- This finding contributes to the understanding of genotype-phenotype correlations in rare chromosomal disorders.

01:49Meiosis I
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 a...
01:33Pleiotropy
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,...
01:17Karyotyping
Describing the number and physical features of chromosomes can reveal abnormalities that underlie genetic diseases. This description is facilitated by special staining techniques that produce a particular banding pattern on each chromosome. State-of-the-art techniques make this approach even more powerful, enabling the detection of individual genes that cause disease.A Simple Chromosome Staining Technique Provides Valuable Scientific InsightSome genetic diseases can be detected by looking at...
01:29Nondisjunction
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.
02:30Genomic Imprinting and Inheritance
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...

01:21Nondisjunction
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 sister...
