It is nice to see other group reached the same gene target and nicely repeated your work when they took a wildly different approach :)
this cool work from Alex Keene lab attempted to use GWAS to locate Excessive daytime sleepiness locus mapped to "rs2787120-tagged locus and its proxies contacted a dense cluster of 12 genes " and one of them include HPCA
