X-chromosome associations do not appear in study pages

I noticed that associations (significant at GW-level) on the X-chromosome do not appear in many ‘study’ pages. For example, rs139120857 (X_14875053_G_A), a SNP in MOSPD2, is
‘significant’ (P=2e-10) in the study GCST011348, yet it does not show up in the study-view of OTG: GCST011348

Our Genetics team explains:

The reason for this is that the first page — X_14875053_G_A — is from the Phewas and shows all the association for a study including chr X.

However, when we detect the lead variants using fine-mapping, we exclude the sex chromosomes, which is why you don’t see them in the study page.
