A pathologist receives a VCF file from a sequencing run. What specific information is found in the 'GT' field of the FORMAT column?
Show answer and explanation
Correct answer: The genotype of the sample (e.g., 0/1, 1/1)
In a Variant Call Format (VCF) file, the 'GT' (Genotype) field encodes the alleles called for a sample. '0/0' indicates homozygous reference, '0/1' indicates heterozygous, and '1/1' indicates homozygous variant. This information is essential for interpreting the genetic status of the patient.
