Genes affected

TCEAL5 (HGNC:22282): (transcription elongation factor A like 5) This gene, which is located on the X chromosome, encodes a protein which contains a BEX (brain expressed X-liked like family) domain. This domain is found in proteins encoded by the TCEAL elongation factor (transcription elongation factor A (SII)-like) gene family also located on the X chromosome. The coding region for this gene is located entirely in the terminal exon. [provided by RefSeq, Sep 2011]

The c.448G>A (p.G150R) alteration is located in exon 3 (coding exon 1) of the TCEAL5 gene. This alteration results from a G to A substitution at nucleotide position 448, causing the glycine (G) at amino acid position 150 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
