Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2021The c.798G>C (p.W266C) alteration is located in exon 7 (coding exon 7) of the SLC1A7 gene. This alteration results from a G to C substitution at nucleotide position 798, causing the tryptophan (W) at amino acid position 266 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
