Bug in HaplotypeCaller：GT is called “./.”，but AD and DP isn't 0
HI, I'd like to report a weird result from HaplotypeCaller.
We have a patient sequenced by targeted sequencing,We expected to see no heterozygous variants called in this locus,it have found the insert ,but GT is "./.", and miss the other information;
Therefore I'm really confused why the substitution has "./." called by the HaplotypeCaller and why it passed the filter.
