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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2024The c.759G>C (p.K253N) 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 759, causing the lysine (K) at amino acid position 253 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
