The remaining 11 genes in the region encode proteins associated with neurologic disorders (APBA2, CHRFAM7A, MTMR10, FAN1), skin and eye pigmentation or development (OCA2, HERC2, TJP1, TRPM1), nephritis (ARHGAP11B, MTMR10, FAN1), and lung disease (ENTREP2, NSMCE3). This evidence concerns the gene OCA2 and nervous system disorder.
