Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2022The c.30C>A (p.N10K) alteration is located in exon 1 (coding exon 1) of the CERS6 gene. This alteration results from a C to A substitution at nucleotide position 30, causing the asparagine (N) at amino acid position 10 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
