Genes affected

NUP93 (HGNC:28958): (nucleoporin 93) The nuclear pore complex is a massive structure that extends across the nuclear envelope, forming a gateway that regulates the flow of macromolecules between the nucleus and the cytoplasm. Nucleoporins are the main components of the nuclear pore complex in eukaryotic cells. This gene encodes a nucleoporin protein that localizes both to the basket of the pore and to the nuclear entry of the central gated channel of the pore. The encoded protein is a target of caspase cysteine proteases that play a central role in programmed cell death by apoptosis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2016]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.07764228 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.4, offset of 30, new splice context is: aatGTaacc. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

PM2

Very rare variant in population databases, with high coverage;

PP5

Variant 16-56833407-G-A is Pathogenic according to our data. Variant chr16-56833407-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 224967.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr16-56833407-G-A is described in Lovd as [Pathogenic].
