Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_StrongBS1BS2

The NM_018230.3(NUP133):​c.3383C>T​(p.Ala1128Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000698 in 1,589,800 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A1128E) has been classified as Uncertain significance.

Genes affected
NUP133 (HGNC:18016): (nucleoporin 133) The nuclear envelope creates distinct nuclear and cytoplasmic compartments in eukaryotic cells. It consists of two concentric membranes perforated by nuclear pores, large protein complexes that form aqueous channels to regulate the flow of macromolecules between the nucleus and the cytoplasm. These complexes are composed of at least 100 different polypeptide subunits, many of which belong to the nucleoporin family. The nucleoporin protein encoded by this gene displays evolutionarily conserved interactions with other nucleoporins. This protein, which localizes to both sides of the nuclear pore complex at interphase, remains associated with the complex during mitosis and is targeted at early stages to the reforming nuclear envelope. This protein also localizes to kinetochores of mitotic cells. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.037867337).
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000723 (104/1437616) while in subpopulation SAS AF= 0.00104 (84/80764). AF 95% confidence interval is 0.00086. There are 2 homozygotes in gnomad4_exome. There are 68 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene
