Summary
Genetic variations in the SUFU gene, specifically the rs10786691 polymorphism, are linked to an increased risk of neural tube defects (NTDs) and encephalocele, particularly in female fetuses within a high-prevalence population.
Area of Science:
- Developmental Biology
- Genetics
- Medical Research
Background:
- Neural tube defects (NTDs) arise from abnormal embryonic development, influenced by genetic and environmental factors.
- The Sonic Hedgehog (SHH) signaling pathway is crucial for neural tube formation.
- Mutations in the SUFU gene, a repressor of SHH signaling, are implicated in NTDs.
Purpose of the Study:
- To investigate the association between SUFU gene polymorphisms and the risk of NTDs in a high-prevalence Chinese population.
- To analyze the relationship between specific SUFU polymorphisms and NTD subtypes, including anencephaly, spina bifida, and encephalocele.
Main Methods:
- A case-control study design was employed.
- Frequencies of polymorphisms at four sites in the SUFU gene were compared between NTD cases and controls.
- Statistical analysis, including odds ratios (OR) and confidence intervals (CI), was used to assess risk.
Main Results:
- The rs10786691 polymorphism in the SUFU gene was significantly associated with an increased risk of NTDs and encephalocele.
- The heterozygous AG genotype of rs10786691 showed a notable association with NTDs (OR=1.60) and encephalocele (OR=2.83).
- This risk was more pronounced in female fetuses (OR=1.88) compared to males, suggesting a gender influence.
Conclusions:
- The SUFU rs10786691 A>G polymorphism may serve as a potential risk factor for NTDs and encephalocele in the studied population.
- The findings suggest that gender may influence the association between SUFU rs10786691 polymorphism and NTD risk.

01:11Genome-wide Association Studies-GWAS
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.

01:05Single Nucleotide Polymorphisms-SNPs
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,...
01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
