Genes affected
TERF1 (HGNC:11728): (telomeric repeat binding factor 1) This gene encodes a telomere specific protein which is a component of the telomere nucleoprotein complex. This protein is present at telomeres throughout the cell cycle and functions as an inhibitor of telomerase, acting in cis to limit the elongation of individual chromosome ends. The protein structure contains a C-terminal Myb motif, a dimerization domain near its N-terminus and an acidic N-terminus. Multiple transcripts of this gene are alternatively spliced products.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.485A>G (p.E162G) alteration is located in exon 3 (coding exon 3) of the TERF1 gene. This alteration results from a A to G substitution at nucleotide position 485, causing the glutamic acid (E) at amino acid position 162 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
