Genes affected
SLC6A17 (HGNC:31399): (solute carrier family 6 member 17) The protein encoded by this gene is a member of the SLC6 family of transporters, which are responsible for the presynaptic uptake of most neurotransmitters. The encoded vesicular transporter is selective for proline, glycine, leucine and alanine. In mouse, the strongest expression of this gene was in cortical and hippocampal tissues where expression increased during embryonic brain development and peaked postnatally. Defects in this gene cause a form of autosomal recessive intellectual disability. [provided by RefSeq, Jul 2017]

SLC6A17-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJun 18, 2024The SLC6A17 c.518A>G variant is predicted to result in the amino acid substitution p.Gln173Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.058% of alleles in individuals of Latino descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
