Genes affected

NUP107 (HGNC:29914): (nucleoporin 107) This gene encodes a member of the nucleoporin family. The protein is localized to the nuclear rim and is an essential component of the nuclear pore complex (NPC). All molecules entering or leaving the nucleus either diffuse through or are actively transported by the NPC. Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 12-68713809-G-A is Pathogenic according to our data. Variant chr12-68713809-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 219129.Status of the report is no_assertion_criteria_provided, 0 stars.
