Genes affected
RABEP1 (HGNC:17677): (rabaptin, RAB GTPase binding effector protein 1) Enables protein domain specific binding activity and protein homodimerization activity. Involved in vesicle-mediated transport. Located in endocytic vesicle and endosome. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]
NUP88 (HGNC:8067): (nucleoporin 88) 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, a family of 50 to 100 proteins, are the main components of the nuclear pore complex in eukaryotic cells. The protein encoded by this gene belongs to the nucleoporin family and is associated with the oncogenic nucleoporin CAN/Nup214 in a dynamic subcomplex. This protein is also overexpressed in a large number of malignant neoplasms and precancerous dysplasias. Alternative splicing results in multiple transcript variants encoding different isoforms.

The c.1178C>T (p.S393L) alteration is located in exon 9 (coding exon 9) of the RABEP1 gene. This alteration results from a C to T substitution at nucleotide position 1178, causing the serine (S) at amino acid position 393 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
