Single nucleotide polymorphisms of PCP pathway related genes participate in the occurrence and development of neural tube defect.
Article in Molecular genetics & genomic medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTo screen the single nucleotide polymorphisms (SNPs) in the coding regions of VANGL and FZD family members related to the plane cell polarity (PCP) signaling pathway in neural tube defects (NTDs) patients, so as to provide theoretical and experimental basis for the prevention and treatment of NTDs by intervening PCP signal transduction.
methods112 NTDs patients were collected as the case group and 112 craniocerebral trauma patients as control. Afterwards, blood genomic DNA was extracted and sequenced. The distribution of SNP alleles and genotypes between case and control groups was analyzed. Finally, the NTD rat model was constructed, and the effect of SNPs on the expression level of VANGL and FZD genes was verified by qRT-PCR.
resultsGC genotype was newly found at VANGL1 c.346G>A, as well as AT genotype in FZD6 c.97A>G. The distribution of VANGL1 c.346g>A allele and genotype was statistically different between the case and control groups (p < 0.05). The newly found genotype GC increased the risk of NTDs (OR = 9.918, 95% CI: 1.234%-79.709%). The results of qRT-PCR showed that the expression level of FZD6 in E11 NTD fetuses were significantly increased (p < 0.05), but there was no obvious difference in the expression of VANGL1.
conclusionWe found a new variant of VANGL1 c.346G>A, whose GC genotype might play an important role in the pathogenesis of NTDs. The SNPs of VANGL1 had no significant effect on its expression level, indicating that it may induce NTDs through other ways. FZD6 was significantly overexpressed in NTDs fetuses.
