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.845C>T (p.P282L) alteration is located in exon 6 (coding exon 6) of the SYNJ2 gene. This alteration results from a C to T substitution at nucleotide position 845, causing the proline (P) at amino acid position 282 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
