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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 07, 2024The c.7496G>T (p.W2499L) alteration is located in exon 53 (coding exon 52) of the TEP1 gene. This alteration results from a G to T substitution at nucleotide position 7496, causing the tryptophan (W) at amino acid position 2499 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
