Saethre-Chotzen syndrome: a broad and variable pattern of skeletal malformations
The Journal of Pediatrics
|December 1, 1977
Summary
This study describes a family with skeletal malformations, suggesting Saethre-Chotzen syndrome has a broader range of symptoms than previously thought, including variable craniosynostosis.
Area of Science:
- Genetics
- Medical Genetics
- Skeletal Dysplasias
Background:
- Saethre-Chotzen syndrome is a genetic disorder characterized by craniosynostosis and other craniofacial abnormalities.
- The typical presentation includes facial asymmetry, delayed fontanel closure, and limb malformations.
- Variability in expressivity can make diagnosis challenging.
Purpose of the Study:
- To describe a family with a complex of skeletal malformations.
- To investigate the phenotypic spectrum of Saethre-Chotzen syndrome.
- To determine if craniosynostosis is a mandatory feature of Saethre-Chotzen syndrome.
Main Methods:
- Clinical examination of 15 affected individuals across five generations.
- Detailed documentation of skeletal malformations.
- Comparison of clinical features with known Saethre-Chotzen syndrome cases.
Main Results:
- A family presented with variable skeletal malformations including asymmetric facies, delayed fontanel closure, brachycephaly, acrocephaly, brachydactyly, syndactyly, and short stature.
- Craniosynostosis was absent or mild in affected family members.
- The observed features were highly similar to Saethre-Chotzen syndrome.
Conclusions:
- Saethre-Chotzen syndrome encompasses a wider range of craniofacial and skeletal malformations than previously recognized.
- Craniosynostosis may not be a consistent feature of Saethre-Chotzen syndrome.
- This family's phenotype expands the understanding of Saethre-Chotzen syndrome's variability.

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.

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...
