Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2024The c.196C>T (p.R66W) alteration is located in exon 4 (coding exon 2) of the CERS4 gene. This alteration results from a C to T substitution at nucleotide position 196, causing the arginine (R) at amino acid position 66 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
