Genes affected

PINX1 (HGNC:30046): (PIN2 (TERF1) interacting telomerase inhibitor 1) Enables telomerase RNA binding activity and telomerase inhibitor activity. Involved in several processes, including negative regulation of DNA biosynthetic process; positive regulation of protein localization to nucleolus; and protein localization to organelle. Acts upstream of or within telomere maintenance via telomerase. Located in several cellular components, including chromosomal region; nuclear lumen; and spindle.

The c.841G>C (p.V281L) alteration is located in exon 7 (coding exon 7) of the PINX1 gene. This alteration results from a G to C substitution at nucleotide position 841, causing the valine (V) at amino acid position 281 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
