Genes affected
SLC38A4 (HGNC:14679): (solute carrier family 38 member 4) SLC38A4 is found predominantly in liver and transports both cationic and neutral amino acids. The transport of cationic amino acids by SLC38A4 is Na(+) and pH independent, while the transport of neutral amino acids is Na(+) and pH dependent (Hatanaka et al., 2001 [PubMed 11342143]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2022The c.1340C>G (p.P447R) alteration is located in exon 15 (coding exon 13) of the SLC38A4 gene. This alteration results from a C to G substitution at nucleotide position 1340, causing the proline (P) at amino acid position 447 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
