Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 23, 2023The c.1382A>C (p.Y461S) alteration is located in exon 15 (coding exon 13) of the SMC6 gene. This alteration results from a A to C substitution at nucleotide position 1382, causing the tyrosine (Y) at amino acid position 461 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
