Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.1670G>A (p.R557Q) alteration is located in exon 9 (coding exon 9) of the SLC1A6 gene. This alteration results from a G to A substitution at nucleotide position 1670, causing the arginine (R) at amino acid position 557 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
