Genes affected

TCEAL2 (HGNC:29818): (transcription elongation factor A like 2) 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. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 28, 2023

The c.14T>A (p.F5Y) alteration is located in exon 3 (coding exon 1) of the TCEAL2 gene. This alteration results from a T to A substitution at nucleotide position 14, causing the phenylalanine (F) at amino acid position 5 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
