Genes affected

TCEAL3 (HGNC:28247): (transcription elongation factor A like 3) This gene encodes a member of the transcription elongation factor A (SII)-like (TCEAL) gene family. Members of this family contain TFA domains and may function as nuclear phosphoproteins that modulate transcription in a promoter context-dependent manner. Multiple family members are located on the X chromosome. Alternative splicing results in multiple transcript variants encoding a single isoform. [provided by RefSeq, Jul 2008]

The c.119G>A (p.G40E) alteration is located in exon 3 (coding exon 1) of the TCEAL3 gene. This alteration results from a G to A substitution at nucleotide position 119, causing the glycine (G) at amino acid position 40 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
