Does the Haplotype Caller perform Linkage Disequilibirum as part of the variant callling algorithm?

Hi,

I'd like to know if the Haplotype Caller perform Linkage Disequilibirum (LD) to decide wether to call a variant or not as part of the variant callling algorithm?

I've read documentation about the Haplotype Caller, but I cannot find anything about LD, so should I assume that it doesn't do LD?

Thank you,
