Genes affected
SLC38A9 (HGNC:26907): (solute carrier family 38 member 9) Enables L-arginine transmembrane transporter activity and L-leucine transmembrane transporter activity. Involved in amino acid transmembrane transport; cellular response to amino acid stimulus; and positive regulation of TOR signaling. Located in late endosome and lysosomal membrane. Is integral component of lysosomal membrane. Colocalizes with Ragulator complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2024The c.1045G>A (p.E349K) alteration is located in exon 11 (coding exon 9) of the SLC38A9 gene. This alteration results from a G to A substitution at nucleotide position 1045, causing the glutamic acid (E) at amino acid position 349 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
