Variant summary

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

The NM_024672.6(THAP9):c.2009C>T(p.Ala670Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000613 in 1,614,012 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 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. A670E) has been classified as Uncertain significance.

The c.2009C>T (p.A670V) alteration is located in exon 5 (coding exon 5) of the THAP9 gene. This alteration results from a C to T substitution at nucleotide position 2009, causing the alanine (A) at amino acid position 670 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
