Genes affected

SYNJ2 (HGNC:11504): (synaptojanin 2) The gene is a member of the inositol-polyphosphate 5-phosphatase family. The encoded protein interacts with the ras-related C3 botulinum toxin substrate 1, which causes translocation of the encoded protein to the plasma membrane where it inhibits clathrin-mediated endocytosis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

The c.925G>A (p.G309R) alteration is located in exon 7 (coding exon 7) of the SYNJ2 gene. This alteration results from a G to A substitution at nucleotide position 925, causing the glycine (G) at amino acid position 309 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
