Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 16, 2024The c.772A>C (p.M258L) alteration is located in exon 7 (coding exon 7) of the SLC17A6 gene. This alteration results from a A to C substitution at nucleotide position 772, causing the methionine (M) at amino acid position 258 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
