A question about VCF format of results from the 'genotype' function.

[zhiyongli1995]

Hi,

When I check my results from the 'genotype' function. There are many "*" symbols in the ALT column. I want to know why it is present here, and if it is biologically meaningful? 

Looking forward to your reply! Best regards!

Example of my question:

chr1    42842   .       T       TT,*  
chr1    42969   .       A       AA,*  
chr1    42993   .       G       GT,*  
chr1    43026   .       TA      T,*   
chr1    43090   .       C       CA,*  
chr1    43333   .       TC      T,*   
chr1    43450   .       AA      A,*   
chr1    43459   .       TA      T,*   
chr1    43488   .       TA      T,*   
chr1    43491   .       A       AGG,* 
chr1    43631   .       TT      T,*   
chr1    43684   .       A       AA,*  
chr1    43709   .       C       CT,*
