Fingerprint Patterns of Down Syndrome Children at Bakhti Kencana SLB and Normal Children at SD Budi Mulia Dua Yogyakarta

Abstract: Dermatoglyphics is not only used to identify criminals, but also useful in the clinical field. There is some evidence that people with chromosome abnormalities like Down Syndrome (trisomy 21), have abnormalities in dermatoglyphics patterns compared to normal people. It can be used to help confirm the diagnosis. The goals are to study the variation and distribution difference of dermatoglyphics and also the difference of Total Ridge Count (TRC) on children with Down Syndrome at SLB Bakhti Kencana and normal children at SD Budi Mulia Dua Yogyakarta. This research uses a cross-sectional study with 2 groups of subjects consisting of 10 people. The dermatoglyphics was taken y sticking both hands that had been marked with purple ink on the paper. Gathered data was analyzed with descriptive analysis and statistical analysis using Chi Square test, Fisher test and independent sample T-test with SPSS 4 for windows. The results show that the highest mean percentage of dermatoglyphics on Down Syndrome children is whorl (55%), on the other hand the highest mean percentage of dermatoglyphics on normal children is loop ulna (53%). There is a significant difference (p<0,05) using the Chi Square test on the distribution of whorl pattern on both hands and whorl on the right hand of children with Down Syndrome at SLB Bakhti Kencana and normal children at SD Budi Mulia Dua Yogyakarta, but the other patterns of dermatoglyphic show no significance. The mean of total ridge countn Down Syndrome (209) was higher than normal children (165,3), using independent sample T-test showing significance at p 0,04. From this research, it can be concluded that there is a significant difference in whorl pattern distribution of both hands and whorl pattern on the right hand between Down Syndrome children at SLB Bakhti Kencana and normal children at SD Budi Mulia Dua Yogyakarta, but the distribution of loops ulna, radial and arch pattern loops on both hands and each hand show no significance. The mean of total ridge count between both population how significant difference.
