Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.1066C>A (p.L356M) alteration is located in exon 9 (coding exon 6) of the SLC7A6 gene. This alteration results from a C to A substitution at nucleotide position 1066, causing the leucine (L) at amino acid position 356 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
