Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.1261C>T (p.R421C) alteration is located in exon 13 (coding exon 10) of the SLC6A12 gene. This alteration results from a C to T substitution at nucleotide position 1261, causing the arginine (R) at amino acid position 421 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
