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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 23, 2022The c.764C>T (p.A255V) alteration is located in exon 7 (coding exon 7) of the PINX1 gene. This alteration results from a C to T substitution at nucleotide position 764, causing the alanine (A) at amino acid position 255 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
