Genes affected

MYH10 (HGNC:7568): (myosin heavy chain 10) This gene encodes a member of the myosin superfamily. The protein represents a conventional non-muscle myosin; it should not be confused with the unconventional myosin-10 (MYO10). Myosins are actin-dependent motor proteins with diverse functions including regulation of cytokinesis, cell motility, and cell polarity. Mutations in this gene have been associated with May-Hegglin anomaly and developmental defects in brain and heart. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

NDEL1 (HGNC:17620): (nudE neurodevelopment protein 1 like 1) Enables identical protein binding activity. Involved in chromosome segregation; positive regulation of GTPase activity; and regulation of intracellular protein transport. Located in kinetochore. Biomarker of schizophrenia.

The c.5743G>C (p.E1915Q) alteration is located in exon 40 (coding exon 39) of the MYH10 gene. This alteration results from a G to C substitution at nucleotide position 5743, causing the glutamic acid (E) at amino acid position 1915 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
