Genes affected

PACSIN2 (HGNC:8571): (protein kinase C and casein kinase substrate in neurons 2) This gene is a member of the protein kinase C and casein kinase substrate in neurons family. The encoded protein is involved in linking the actin cytoskeleton with vesicle formation by regulating tubulin polymerization. Alternative splicing results in multiple transcript variants.

The c.1355A>G (p.E452G) alteration is located in exon 11 (coding exon 10) of the PACSIN2 gene. This alteration results from a A to G substitution at nucleotide position 1355, causing the glutamic acid (E) at amino acid position 452 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
