Identification of a novel nonsynonymous mutation of EYA1 disrupting splice site in a Korean patient with BOR syndrome.
Article in Molecular biology reports, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The EYA1 gene is known as the causative gene of BOR (Branchio-oto-renal) syndrome which is a genetic disorder associated with branchial cleft cysts of fistulae, hearing loss, ear malformation, and renal anomalies. Although approximately 40% of patients with BOR syndrome have mutations in the EYA1 gene and over 130 disease-causing mutations in EYA1 have been reported in various populations, only a few mutations have been reported in Korean families. In this study, genetic analysis of the EYA1 gene was performed in a Korean patient diagnosed with BOR syndrome and his parents. A de novo novel missense mutation, c.418G>A, located at the end of exon 6, changed glycine to serine at amino acid position 140 (p.G140S) and was suspected to affect normal splicing. Our in vitro splicing assay demonstrated that this mutation causes exon 6 skipping leading to frameshift and truncation of the protein to result in the loss of eyaHR. To the best of our knowledge, this is the first report revealing that a missense mutation in the exon disturbs normal splicing as a result of a substitution of the last nucleotide of an exon in EYA1.
