New database software for calculating statistical values in forensic deoxyribonucleic acid (DNA) typing is presented. This software can be applied to various tasks including (i) person identification, (ii) paternity testing or maternity testing, (iii) full sibling testing using autosomal short tandem repeat (STR), (iv) half sibling testing using autosomal STR, (v) maternal lineage testing using mitochondrial DNA analysis, (vi) paternal lineage testing using Y-STR analysis and (vii) sibling analysis of two females having the same biological father or relationship testing between paternal grandmother and granddaughter by using X-STR. Various DNA data such as autosomal STR, Y-STR, X-STR and mitochondrial DNA can be stored in the database. DNA data can be searched by sorted name or sorted family code. This program is suited for estimating statistical values in the Thai population because the Thai allele frequency database is used for background calculations. In addition, the printout from this software can be used as a DNA typing report. All necessary forensic statistical values and fundamental interpretation are also included in this report.
