HOGA1 variants in Chinese patients with primary hyperoxaluria type 3: genetic features and genotype-phenotype relationships.
Article in World journal of urology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeThe aim of our study is to describe the genetic features and correlation between the genotype and phenotype of Chinese patients with primary hyperoxaluria type 3 (PH3).
methodsThe genetic and clinical data of PH3 patients in our cohort were collected and analyzed retrospectively. All published studies of Chinese PH3 populations between January 2010 and November 2022 were searched and enrolled based on inclusive standards.
resultsA total of 60 Chinese PH3 patients (21 cases from our cohort and 39 cases from previous studies) were included. The mean age of onset was 1.62 ± 1.35 (range 0.4-7) years. A total of 29 different variants in the HOGA1 gene were found. The mutations were most commonly clustered in exons 1, 6, and 7. Among the genotypes, exon 6 skipping (c.834G > A and c.834_834 + 1GG > TT mutations) was the most common, followed by c.769 T > G; the allele frequencies (AFs) were 48.76% and 12.40%, respectively. Patients homozygous for exon 6 skipping exhibited a median age of onset of 0.67 (0.58-1) years, which was significantly lower than that observed among heterozygotes and nonexon 6 skipping patients (p = 0.021). A total of 22.5% (9/40) of PH3 patients had a decreased estimated glomerular filtration rate, and one patient with homozygous exon 6 skipping developed end-stage renal disease.
conclusionsA hotspot mutation, potential hotspot mutation and genotype-phenotype correlation were found in Chinese PH3 patients. This study expands the mutational spectrum and contributes to the understanding of genotypic profiles of PH3, which may provide a potential diagnostic and therapeutic target.
