Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 24, 2023The c.55C>T (p.R19W) alteration is located in exon 2 (coding exon 1) of the ELAC1 gene. This alteration results from a C to T substitution at nucleotide position 55, causing the arginine (R) at amino acid position 19 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
