Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_017884.6(PINX1):c.733G>A(p.Ala245Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000186 in 1,613,890 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A245S) has been classified as Uncertain significance.

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.733G>A (p.A245T) alteration is located in exon 7 (coding exon 7) of the PINX1 gene. This alteration results from a G to A substitution at nucleotide position 733, causing the alanine (A) at amino acid position 245 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
