Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2023The c.598A>G (p.I200V) alteration is located in exon 6 (coding exon 6) of the CERS6 gene. This alteration results from a A to G substitution at nucleotide position 598, causing the isoleucine (I) at amino acid position 200 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
