Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.649G>A (p.G217R) alteration is located in exon 5 (coding exon 5) of the SLC1A6 gene. This alteration results from a G to A substitution at nucleotide position 649, causing the glycine (G) at amino acid position 217 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
