Genes affected

RMDN1 (HGNC:24285): (regulator of microtubule dynamics 1) Enables microtubule binding activity. Predicted to be involved in attachment of mitotic spindle microtubules to kinetochore and mitotic spindle organization. Located in mitotic spindle pole and spindle microtubule. [provided by Alliance of Genome Resources, Apr 2022]

RMDN1 links:

WWP1 (HGNC:17004): (WW domain containing E3 ubiquitin protein ligase 1) WW domain-containing proteins are found in all eukaryotes and play an important role in the regulation of a wide variety of cellular functions such as protein degradation, transcription, and RNA splicing. This gene encodes a protein which contains 4 tandem WW domains and a HECT (homologous to the E6-associated protein carboxyl terminus) domain. The encoded protein belongs to a family of NEDD4-like proteins, which are E3 ubiquitin-ligase molecules and regulate key trafficking decisions, including targeting of proteins to proteosomes or lysosomes. Alternative splicing of this gene generates at least 6 transcript variants; however, the full length nature of these transcripts has not been defined. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.752C>T (p.A251V) alteration is located in exon 8 (coding exon 8) of the RMDN1 gene. This alteration results from a C to T substitution at nucleotide position 752, causing the alanine (A) at amino acid position 251 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
