Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.1423C>T (p.R475W) alteration is located in exon 11 (coding exon 8) of the SLC7A6 gene. This alteration results from a C to T substitution at nucleotide position 1423, causing the arginine (R) at amino acid position 475 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
