Genes affected
SLC38A1 (HGNC:13447): (solute carrier family 38 member 1) Amino acid transporters play essential roles in the uptake of nutrients, production of energy, chemical metabolism, detoxification, and neurotransmitter cycling. SLC38A1 is an important transporter of glutamine, an intermediate in the detoxification of ammonia and the production of urea. Glutamine serves as a precursor for the synaptic transmitter, glutamate (Gu et al., 2001 [PubMed 11325958]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 27, 2022The c.445G>A (p.V149I) alteration is located in exon 7 (coding exon 5) of the SLC38A1 gene. This alteration results from a G to A substitution at nucleotide position 445, causing the valine (V) at amino acid position 149 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
