Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2024The c.997C>T (p.P333S) alteration is located in exon 9 (coding exon 9) of the NSUN6 gene. This alteration results from a C to T substitution at nucleotide position 997, causing the proline (P) at amino acid position 333 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
