Identification of a silent point mutation in the LDL-receptor gene by direct DNA sequencing.
Article in Klinische Wochenschrift, 1991. 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
To study the allelic variation at the human LDL-receptor gene locus in a number of individuals with familial hypercholesterolemia, a protocol was applied for direct sequence analysis of genomic DNA. The asymmetric polymerase chain reaction (PCR) was used to synthesize single-stranded DNA. Sequencing was carried out with modified T7 DNA polymerase (Sequenase version 2.0, United States Biochemical) after purification of the amplification product with a glass powder adhesion method. The method is sensitive enough to identify the heterozygous state of allelic variation and bypasses cumbersome cloning and subcloning procedures. Here we report the occurrence of a guaninine-to-adenine change in the codon for amino acid 655. However, the glycine residue is not replaced by the base change at this position, and the mutation observed here does not represent the underlying genetic defect of the LDL-receptor defect in this individual. Preliminary data suggest that this mutation represents a rare genetic variation.
