Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2021The c.53A>G (p.N18S) alteration is located in exon 1 (coding exon 1) of the CERS6 gene. This alteration results from a A to G substitution at nucleotide position 53, causing the asparagine (N) at amino acid position 18 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
