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]

The c.784G>A (p.G262S) alteration is located in exon 10 (coding exon 8) of the SLC38A9 gene. This alteration results from a G to A substitution at nucleotide position 784, causing the glycine (G) at amino acid position 262 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
