Plink effect allele

Webb7 apr. 2024 · An allele is one of two or more different forms of a DNA variant (Fig. 1), which is a permanent change in the DNA sequence. If such a change occurs in the coding sequence of a gene, the change may affect the amino acid sequence and function of the protein product. WebbMinor allele frequency files. Minor allele frequency files format is the same as that of PLINK. The columns are: CHR Chromosome number of the SNP. SNP rs ID of the SNP (e.g. rs19800301). A1 Non-effect allele. A2 Effect allele (encoded as 1 in PLINK bed file). MAF Minor allele frequency; NCHROBS Number of samples times 2.
