Focal facial dermal dysplasia type 4: identification of novel CYP26C1 mutations in unrelated patients.
Article in Journal of human genetics, 2018. 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
The focal facial dermal dysplasias (FFDDs) are a group of rare inherited developmental disorders characterized by congenital scar-like atrophic lesions in the bitemporal (FFDD1, 2, and 3) or preauricular (FFDD4) areas. FFDD4 is an autosomal-recessive trait characterized by preauricular skin defects without additional dysmorphic findings. Previously, only two CYP26C1 mutations in four unrelated patients with FFDD4 were reported. Here, we report two additional unrelated FFDD4 patients with four CYP26C1 mutations including three novel lesions: a missense mutation, c.230G>C (p.Arg77Pro), and two splice-site mutations, c.1191+1G>T (IVS5(+1)G>T) and c.1191+2insT (IVS5(+2)insT). In silico analyses predicted all three mutations as pathogenic. Compound heterozygosity was validated through parental studies. These results provide further evidence that CYP26C1 mutations are the molecular genetic basis of FFDD4. Identification of additional cases by dermatologists, pediatricians, and medical geneticists will lead to further understanding of the clinical spectrum of FFDD4 and define its molecular genetic heterogeneity.
