Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2024The c.877A>T (p.T293S) alteration is located in exon 4 (coding exon 3) of the ELAC1 gene. This alteration results from a A to T substitution at nucleotide position 877, causing the threonine (T) at amino acid position 293 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
