Genes affected

ELL3 (HGNC:23113): (elongation factor for RNA polymerase II 3) Predicted to enable cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription, DNA-templated and transcription by RNA polymerase II. Located in several cellular components, including chromosome; cytosol; and nuclear lumen. Part of transcription elongation factor complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Dec 13, 2022

The c.348G>A (p.M116I) alteration is located in exon 4 (coding exon 4) of the ELL3 gene. This alteration results from a G to A substitution at nucleotide position 348, causing the methionine (M) at amino acid position 116 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
