Genes affected
SLC6A14 (HGNC:11047): (solute carrier family 6 member 14) This gene encodes a member of the solute carrier family 6. Members of this family are sodium and chloride dependent neurotransmitter transporters. The encoded protein transports both neutral and cationic amino acids. This protein may also function as a beta-alanine carrier. Mutations in this gene may be associated with X-linked obesity. A pseudogene of this gene is found on chromosome X.[provided by RefSeq, May 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2023The c.325A>T (p.R109W) alteration is located in exon 3 (coding exon 3) of the SLC6A14 gene. This alteration results from a A to T substitution at nucleotide position 325, causing the arginine (R) at amino acid position 109 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
