Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.775A>G (p.S259G) alteration is located in exon 4 (coding exon 4) of the SLC7A6OS gene. This alteration results from a A to G substitution at nucleotide position 775, causing the serine (S) at amino acid position 259 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
