What means is " * " in alternative allele ?
I ran HaplotypeCaller about multi-samples to obtain gvcf and combined multi-samples's gvcf using GenotypeGVCF.
As result of GenotypeGVCF, I obtain joint,vcf.
However, I couldn't understand contents in my joint.vcf,
10 134767 rs12768206 A G,* 11674.12 . AC=30,4;AF=0.246,0.033;AN=122;BaseQRankSum=-1.260e+00;ClippingRankSum=0.458;DB;DP=1662;FS=1.110;InbreedingCoe
What means is " * " in alternative allele column and What is genotype?
