Abstract

Bone is a dynamic network that has a complex cellular regeneration system. A forensic examination is closely related to examining the physiology and anatomy of the living body, including bone as the evidence in DNA testing. This study aims to analyze the DNA extraction on human bone powder using PrepFiler® BTA Forensic DNA Extraction Kit. DNA was isolated from compact and cancellous bone tissue from decomposed human bodies. The bones were soaked in NaOCl for 5 min, then rinsed with nuclease-free water. The bone was sawn into bone powder and then extracted using 220 µl of BTA lysis, 7 µl of Prot-K, and 3 µl of DTT. PrepfilerTM Lysis Buffer was added as much as 300 µl then homogenized by vortex and spin using a centrifuge. Spectrophotometry was performed to measure the DNA concentration using an absorbance from 230 nm to 320 nm. The results showed that the DNA purity values of the three samples of compact and cancellous bone powder used were close to good quality: 2.08, 2.06, and 1.71, respectively. Low concentration values obtained from compact bone samples were 14.2 ng/µL and 11.9 ng/µL respectively, which inversely proportional to cancellous bones by 59 ng/µL.

Abstract

ABSTRACT Piebaldism is a disorder in the area of ​​the body caused by an autosomal genetic predominance of the development of melanocytes.The method used in this study is a qualitative method which aims to determine the variation of the KIT-c gene present in the To Balo mucosa samples.The results of this study indicate thatThe change is caused by a point mutation process where in patients with piabeldism the nucleotide bases of sequence 1391 and 1392 undergo changes, where the normal nucleotide base adenine (A) changes to cytosine (C) and cytosine (C) changes to adenine (A). So it can be concluded that the To Balo community in Bulo-Bulo village, Pujananting District, Barru Regency, South Sulawesi suffers from an autosomal dominant hereditary disease or piebaldism.
