Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 10, 2024The c.820C>T (p.R274W) alteration is located in exon 6 (coding exon 6) of the SLC2A6 gene. This alteration results from a C to T substitution at nucleotide position 820, causing the arginine (R) at amino acid position 274 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
