A49T, R227Q and TA repeat polymorphism of steroid 5 alpha-reductase type II gene and Hypospadias risk in North Indian children.
Article in Meta gene, 2015. 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
BACKGROUND/
aimsHypospadias is a common congenital error of genital development, the frequency of which is increasing. As androgens have a significant role in the development of the male urethra, we sought to investigate the association between functional polymorphisms of SRD5A2 gene in relation to hypospadias.
methodsWe examined DNA samples of 96 cases and 105 controls for SRD5A2-A49T, R227Q and TA repeat gene polymorphisms.
resultAbsence of 49T locus and 227Q locus was observed in the present study. At the (TA) n repeat site, TA (0) allele was observed to be the most common allele in both cases (91.7%) and controls (90%). TA (9/9) genotype exhibited an odds ratio of 3.03 (95% C.I. = 0.18-50.14, p = 0) with respect to only middle phenotypes. Analysis of the demographic data depicted the agricultural background aspect of the parents of the cases. 72.27% of the cases (affected with Hypospadias) have parents having agriculture as a primary occupation.
conclusionAs longer TA repeats are associated with lower enzymatic activity and lower DHT levels as reported among Caucasians, this polymorphism may have an effect (rather small) in predisposing the population of the present study to the risk of Hypospadias of lesser severity. Due to small sample size, the 3.03 O.R. is not significant and a larger sample is needed to validate the results. Large scale screening of Hypospadias and other 46 X,Y disorders of sexual development is needed especially in India, where the majority of the population is from agricultural background. The results of the present study are likely to assist the health planners to initiate screening of Hypospadias among the farmer community to combat the risk of Hypospadias.
