Genes affected

TEP1 (HGNC:11726): (telomerase associated protein 1) This gene product is a component of the ribonucleoprotein complex responsible for telomerase activity which catalyzes the addition of new telomeres on the chromosome ends. The telomerase-associated proteins are conserved from ciliates to humans. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

The c.7492G>A (p.E2498K) alteration is located in exon 53 (coding exon 52) of the TEP1 gene. This alteration results from a G to A substitution at nucleotide position 7492, causing the glutamic acid (E) at amino acid position 2498 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
