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 GeneticsJul 06, 2021The c.740C>T (p.T247I) alteration is located in exon 9 (coding exon 7) of the SLC38A9 gene. This alteration results from a C to T substitution at nucleotide position 740, causing the threonine (T) at amino acid position 247 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
