missing hgnc id for several variants

### Describe the bug

When querying the variation/normalize endpoint for some x-chromosome variants, no gene symbols or gene IDs were returned. Here are the variants:

X-118725211-A-G
X-101395767-C-T
X-10096159-C-T

I used the docker version of the normalizer, and I had GRCh37 input data.

example of output:

{

}
}

### Steps to reproduce

1. start docker version of variation normalizer
2. look at this result: http://localhost:8001/variation/normalize?q=X-10096159-C-T&hgvs_dup_del_mode=default&input_assembly=GRCh37

### Expected behavior

I expected an output similar to this:

http://localhost:8001/variation/normalize?q=X-2408485-G-C&hgvs_dup_del_mode=default&input_assembly=GRCh37
