Slc38a4 (Ata3) (solute carrier family 38, member 4, amino acid transportsystem A3) is paternally
expressed in embryonic day-15.5 and in all adult tissues examined except the liver and viscera (Mizuno
Y et al. 2002; Smith RJ et al. 2003). Paternal but not maternal knockout of Slc38a4 caused placental hypoplasia associated with reduced fetal weight (Matoba S et al, 2019).
et al (2003) reported that the CpG island approximately 1.2 kb downstream of exon 1 was
maternally methylated in adult liver.
The human orthologue SLC38A4 is found on chromosome 12 and has not yet been investigated for
