Normalization works on some NCBI 36 Variants

[jarbesfeld]

Describe the bug

My understanding is that the variation normalizer is restricted to support variants described on GRCh37/38, but it appears to currently support some variant types on NCBI 36 too.

}

Expected behavior

A warning message would be returned reporting that variants on NCBI 36 are not supported. The returned variant would be described on the NCBI 36 reference sequence.
