Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2023The c.1366A>G (p.I456V) alteration is located in exon 11 (coding exon 11) of the NSUN6 gene. This alteration results from a A to G substitution at nucleotide position 1366, causing the isoleucine (I) at amino acid position 456 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
