Genes affected

TCEAL4 (HGNC:26121): (transcription elongation factor A like 4) This gene encodes a member of the transcription elongation factor A (SII)-like (TCEAL) gene family. This family is comprised of nuclear phosphoproteins that modulate transcription in a promoter context-dependent manner. Multiple family members are located on the X chromosome. Alternatively splicing results in multiple transcript variants. There is a pseudogene for this gene on chromosome 13. [provided by RefSeq, Apr 2015]

Collection Method: clinical testing

The c.8A>G (p.K3R) alteration is located in exon 3 (coding exon 1) of the TCEAL4 gene. This alteration results from a A to G substitution at nucleotide position 8, causing the lysine (K) at amino acid position 3 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
