Genes affected

SLC6A18 (HGNC:26441): (solute carrier family 6 member 18) The SLC6 family of proteins, which includes SLC6A18, act as specific transporters for neurotransmitters, amino acids, and osmolytes like betaine, taurine, and creatine. SLC6 proteins are sodium cotransporters that derive the energy for solute transport from the electrochemical gradient for sodium ions (Hoglund et al., 2005 [PubMed 16125675]).[supplied by OMIM, Apr 2010]

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.384 is higher than 0.05.
