Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.1474C>T (p.R492W) alteration is located in exon 15 (coding exon 12) of the SLC6A12 gene. This alteration results from a C to T substitution at nucleotide position 1474, causing the arginine (R) at amino acid position 492 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
