Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2024The c.355G>A (p.E119K) alteration is located in exon 5 (coding exon 5) of the POLR1E gene. This alteration results from a G to A substitution at nucleotide position 355, causing the glutamic acid (E) at amino acid position 119 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
