Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2021The c.1191G>T (p.Q397H) alteration is located in exon 10 (coding exon 10) of the NSUN6 gene. This alteration results from a G to T substitution at nucleotide position 1191, causing the glutamine (Q) at amino acid position 397 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
