Although we found no overlap between the true HF eQTLs and AGA genetic risk loci, which might be an expected finding, considering that the occipital scalp is not susceptible to balding, the overlapping eGene ATP2B4 provides a potential novel candidate gene for AGA, as the reported gene for the region is so far SOX13 [25, 26]. Here, ATP2B4 is linked to hydrops fetalis.
