(A) Schematic representation of the SLC38A8 protein with 11 transmembrane domains and location of amino acid changes in relation to the protein domains. Mutations in italics and with a solid black outline are ones reported in this study. Transmembrane domain 6 has recurrent missense mutations. c.995dupG: p.(W333Mfs*35) was a recurrent frameshift mutation reported in this study that was observed in three separate Korean families. Similarly, p.I32S is a recurrent mutation (reported in six separate families) observed in both Indian and Karaite Jewish ethnicities.
