Genes affected

MISP (HGNC:27000): (mitotic spindle positioning) The protein encoded by this gene is an actin-bundling protein involved in determining cell morphology and mitotic progression. The encoded protein is required for the proper positioning of the mitotic spindle. Two transcript variants, one protein-coding and the other non-protein coding, have been found for this gene.

The c.286C>T (p.R96C) alteration is located in exon 2 (coding exon 1) of the MISP gene. This alteration results from a C to T substitution at nucleotide position 286, causing the arginine (R) at amino acid position 96 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
