Other variants dominantly associated with ME/CFS were laminin subunit alpha 2 (LAMA2), protein tyrosine phosphatase receptor type D (PTPRD), REX4 homologue, 3′-5′ exonuclease (REXO4), solute carrier family 38 member 2 (SLC38A2), arylsulfatase G (ARSG), zinc finger protein 266 (ZNF266), and cytochrome P450 family 4 subfamily F member 8 (CYP4F8). Here, REXO4 is linked to myalgic encephalomeyelitis/chronic fatigue syndrome.
