ARR3 and myopia: Xiao et al. described three families with East Asian ethnicity and early onset high myopia caused by three different mutations, namely, two missense mutations (NM_004312.2(ARR3):c.893C>A (p.Ala298Asp) and NM_004312.2(ARR3):c.239T>C (p.Leu80Pro)) and a nonsense mutation (NM_004312.2:(ARR3)c.298C>T (pArg100*)), which was different from our identified nonsense and frameshift mutations (Xiao et al., 2016).
