USA: STR Allele Frequencies from United States

In mispitools: Missing Person Identification Tools

STR Allele Frequencies from United States

Description

Population allele frequency data for 29 autosomal Short Tandem Repeat (STR) markers from the United States population. Includes both core CODIS loci and extended markers.

Usage

data(USA)

Format

A data frame with 97 rows (alleles) and 30 columns. First column is Allele (repeat number), remaining columns are allele frequencies for each STR marker.

Details

This dataset contains allele frequencies for 29 STR markers: CSF1PO, D10S1248, D12S391, D13S317, D16S539, D18S51, D19S433, D1S1656, D21S11, D22S1045, D2S1338, D2S441, D3S1358, D5S818, D6S1043, D7S820, D8S1179, F13A01, F13B, FESFPS, FGA, LPL, Penta_C, Penta_D, Penta_E, SE33, TH01, TPOX, vWA.

This dataset is compatible with the expanded CODIS core loci and includes additional markers for higher discrimination power.

Source
