Genes affected

MOB1B (HGNC:29801): (MOB kinase activator 1B) The protein encoded by this gene is similar to the yeast Mob1 protein. Yeast Mob1 binds Mps1p, a protein kinase essential for spindle pole body duplication and mitotic checkpoint regulation. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

Ambry Genetics

Oct 01, 2024

The c.5G>A (p.S2N) alteration is located in exon 1 (coding exon 1) of the MOB1B gene. This alteration results from a G to A substitution at nucleotide position 5, causing the serine (S) at amino acid position 2 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
