Genes affected

MYO16 (HGNC:29822): (myosin XVI) This gene encodes an unconventional myosin protein. The encoded protein has been proposed to act as a serine/threonine phosphatase-1 targeting or regulatory subunit. Studies in a rat cell line suggest that this protein may regulate cell cycle progression. A variant within this gene may be associated with susceptibility to schizophrenia and elevated expression of this gene has been observed in the frontal cortex of human schizophrenia patients.

The c.638G>T (p.R213L) alteration is located in exon 6 (coding exon 6) of the MYO16 gene. This alteration results from a G to T substitution at nucleotide position 638, causing the arginine (R) at amino acid position 213 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
