Genes affected

MOB1A (HGNC:16015): (MOB kinase activator 1A) The protein encoded by this gene is a component of the Hippo signaling pathway, which controls organ size and tumor growth by enhancing apoptosis. Loss of the encoded protein results in cell proliferation and cancer formation. The encoded protein is also involved in the control of microtubule stability during cytokinesis. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2015]

The c.647G>A (p.R216K) alteration is located in exon 6 (coding exon 6) of the MOB1A gene. This alteration results from a G to A substitution at nucleotide position 647, causing the arginine (R) at amino acid position 216 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
