Variant summary

Our verdict is Benign. The variant received -17 ACMG points: 1P and 18B. PP2BP4_ModerateBP6_Very_StrongBS1BS2

The NM_018105.3(THAP1):​c.421G>A​(p.Asp141Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000812 in 1,614,102 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D141G) has been classified as Uncertain significance.

Genes affected
THAP1 (HGNC:20856): (THAP domain containing 1) The protein encoded by this gene contains a THAP domain, a conserved DNA-binding domain. This protein colocalizes with the apoptosis response protein PAWR/PAR-4 in promyelocytic leukemia (PML) nuclear bodies, and functions as a proapoptotic factor that links PAWR to PML nuclear bodies. Alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -17 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 12 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 1.3716 (below the threshold of 3.09). Trascript score misZ: 2.0485 (below the threshold of 3.09). GenCC associations: The gene is linked to torsion dystonia 6.
BP4
Computational evidence support a benign effect (MetaRNN=0.07263759).
BP6
Variant 8-42838183-C-T is Benign according to our data. Variant chr8-42838183-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 448685.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000407 (62/152214) while in subpopulation AFR AF = 0.0014 (58/41532). AF 95% confidence interval is 0.00111. There are 0 homozygotes in GnomAd4. There are 31 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 62 AD gene.
