Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2023The c.406C>T (p.R136W) alteration is located in exon 5 (coding exon 5) of the ELOVL2 gene. This alteration results from a C to T substitution at nucleotide position 406, causing the arginine (R) at amino acid position 136 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
