Summary
Syndromic Robin sequence (RS) is more common than previously thought and requires more airway support. Early identification of associated syndromes, like Stickler syndrome, is crucial for effective patient management.
Area of Science:
- Craniofacial anomalies
- Genetics
- Pediatric care
Background:
- Robin sequence (RS) is a congenital condition affecting facial development.
- The prevalence and syndromic associations of RS require further investigation.
- Understanding these associations impacts clinical management and patient outcomes.
Purpose of the Study:
- To determine the prevalence of syndromic Robin sequence (RS) in the UK.
- To compare airway and feeding management needs between syndromic and non-syndromic RS patients.
- To assess the association between syndromic status and the need for airway/feeding adjuncts.
Main Methods:
- Prospective national multicenter study within UK specialist cleft services.
- Inclusion of 259 participants with RS and comparison with 548 participants with cleft palate only (CPO).
- Primary outcome: presence of a syndrome; Secondary outcomes: use of airway and feeding adjuncts.
Main Results:
- 28% of RS patients had an associated syndrome, most commonly Stickler syndrome (27%).
- Syndromic RS patients showed significantly higher rates of airway adjunct use (OR 2.02) compared to non-syndromic RS.
- No significant difference in feeding adjunct use between syndromic and non-syndromic RS groups.
Conclusions:
- Syndromic status significantly impacts the management of Robin sequence patients.
- Early identification of syndromes in RS is vital to prevent complications from missed diagnoses.
- Mandatory ophthalmological and genetic screening for Stickler syndrome in all RS patients is recommended.

Genome-wide Association Studies-GWAS
14.0K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Single Nucleotide Polymorphisms-SNPs
15.6K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Bias in Epidemiological Studies
502
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Sex-linked Disorders
102.6K
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.

Pleiotropy
40.8K
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,...

Incomplete Dominance
25.1K
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.
