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.6845C>T (p.A2282V) alteration is located in exon 48 (coding exon 47) of the TEP1 gene. This alteration results from a C to T substitution at nucleotide position 6845, causing the alanine (A) at amino acid position 2282 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
