Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2024The c.1670C>T (p.S557L) alteration is located in exon 10 (coding exon 9) of the SLC6A16 gene. This alteration results from a C to T substitution at nucleotide position 1670, causing the serine (S) at amino acid position 557 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
