Bromodomain-containing protein 2 gene polymorphism among patients with photosensitive epilepsy in Indonesia.

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
objectivesGenetic-associated epilepsy in the Indonesian population is rarely discussed, and no study was specifically studied about photosensitive epilepsy. The fundamental goal of this research endeavor was to evaluate whether the single nucleotide polymorphism (SNP) of the Bromodomain-Containing Protein 2 (BRD2) gene gives vulnerability to photosensitive epilepsy among Indonesian descent.
methodsThis observational case-control study includes patients of Indonesian descent with Javanese ancestry. Clinical and neurophysiological data, along with electroencephalographic (EEG) recordings, were used to diagnose epilepsy and photosensitive epilepsy. Blood samples were collected and analyzed for BRD2 gene SNPs (rs206781, rs188245, and rs15912) using polymerase chain reaction (PCR), electrophoresis, and the Sanger sequencing method.
resultsThis study included 27 participants, consisting of 17 patients in the epilepsy group (nine patients with photosensitive epilepsy and eight patients without photosensitive epilepsy) and 10 patients in the non-epilepsy group. Significant statistical differences were found in genotype (rs206781, p = 0.008 and rs188245, p = 0.004) and allele frequencies (rs206781, p < 0.001 and rs188245, p < 0.001) of the BRD2 gene in Indonesian descent with Javanese race patients diagnosed with photosensitive epilepsy and in those without this condition. SIGNIFICANCE: Our study corroborates the observation that genetic diversity within the BRD2 locus (rs206781 and rs188245) is associated with PE in Indonesian descendants of the Javanese race. To acquire a complete knowledge of the development of photosensitive epilepsy, further polymorphism studies at other SNP locations or genes are necessary. PLAIN LANGUAGE SUMMARY: This study investigated whether genetic differences in the BRD2 gene were linked to photosensitive epilepsy (a type of epilepsy triggered by visual stimuli like flashing lights) in individuals of Indonesian Javanese descent. We analyzed deoxyribonucleic acid (DNA) samples from patients with epilepsy, including those with photosensitive epilepsy, and found that certain variations in the BRD2 gene were significantly more common in people with photosensitive epilepsy. These findings imply that genetic factors, specifically variations in the BRD2 gene, could elevate the risk of individuals in this population experiencing photosensitive epilepsy.
