Summary
This summary is machine-generated.Currarino syndrome, a rare genetic disorder, was identified in two siblings with an unbalanced translocation t(7;21)(q36.2;p11.3)mat. This genetic finding is crucial for diagnosing rare conditions and informing family genetic counseling.
Area Of Science
- Medical Genetics
- Clinical Dysmorphology
- Human Genetics
Background
- Currarino syndrome is a rare inherited disorder characterized by sacral agenesis, anorectal malformation, and presacral mass.
- It is typically caused by mutations in the MNX1 gene and presents with variable expressivity, often underdiagnosed.
- This syndrome is seldom reported in adults and is frequently discovered incidentally.
Purpose Of The Study
- To report two siblings with an incomplete form of Currarino syndrome.
- To investigate the genetic basis of the syndrome in these patients.
- To highlight the role of cytogenetics in diagnosing rare genetic disorders.
Main Methods
- Banding cytogenetics was employed to analyze the chromosomal structure.
- Molecular cytogenetics was utilized for detailed characterization of the genetic anomaly.
- Karyotyping was performed to identify chromosomal abnormalities.
Main Results
- An unbalanced translocation, t(7;21)(q36.2;p11.3)mat, was identified in both affected siblings.
- The translocation resulted in a deletion of the 7q36 region in both children.
- This represents the first reported case of Currarino syndrome in Morocco due to this specific unbalanced translocation and 7q36 deletion.
Conclusions
- Cytogenetic analysis is vital for diagnosing rare genetic syndromes like Currarino syndrome.
- The identification of this specific translocation provides valuable insights for genetic counseling.
- This case expands the known genetic mechanisms underlying Currarino syndrome and its presentation.

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...
Overview
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.

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Y chromosome mutations are called “Y-linked” and only affect males since they alone carry a copy of that chromosome. Mutations to the relatively small Y chromosome can impact male sexual function and secondary sex characteristics. Y-chromosome infertility is a disorder that affects...
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
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,...
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
According to Mendel, organisms with both copies or a single copy of the dominant allele display a...
