Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.1395A>C (p.K465N) alteration is located in exon 11 (coding exon 11) of the NSUN6 gene. This alteration results from a A to C substitution at nucleotide position 1395, causing the lysine (K) at amino acid position 465 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
