This study found that specific genetic variations in Vitamin D pathway genes are associated with schizophrenia susceptibility. Low Vitamin D levels were also prevalent in schizophrenia patients, suggesting a potential link.
Area of Science:
- Neurogenetics
- Nutritional Psychiatry
- Molecular Biology
Background:
- Schizophrenia (SZ) is a complex neurodevelopmental disorder influenced by genetic and environmental factors.
- Single nucleotide polymorphisms (SNPs) are linked to SZ susceptibility.
- Vitamin D (VD) plays a crucial role in brain health and function.
Purpose of the Study:
- To investigate the association between eight SNPs in VD pathway genes (CYP2R1, CYP27B1, CYP24A1, VDR) and schizophrenia.
- To determine if VD levels are associated with schizophrenia.
Main Methods:
- A case-control study involving 200 SZ patients and 200 healthy controls.
- Genotyping of eight SNPs using tetra-amplification refractory mutation system-polymerase chain reaction.
- Analysis of serum 25(OH)D levels.
Main Results:
- Significant associations were found between SZ and three SNPs: CYP2R1 (rs10741657), CYP27B1 (rs10877012), and CYP24A1 (rs6013897).
- Specific genotypes (AA for rs10741657, TT for rs10877012, AA for rs6013897) and alleles were more frequent in SZ patients.
- Low serum VD levels were more prevalent in SZ patients compared to controls.
Conclusions:
- CYP2R1, CYP27B1, and CYP24A1 gene polymorphisms may be associated with schizophrenia susceptibility.
- A potential protective effect of VD and the rs6013897 SNP was observed.
- Low serum Vitamin D levels are linked to schizophrenia, warranting further investigation.
