Genes affected

SYNPO (HGNC:30672): (synaptopodin) Synaptopodin is an actin-associated protein that may play a role in actin-based cell shape and motility. The name synaptopodin derives from the protein's associations with postsynaptic densities and dendritic spines and with renal podocytes (Mundel et al., 1997 [PubMed 9314539]).[supplied by OMIM, Mar 2008]

The c.455G>A (p.R152Q) alteration is located in exon 3 (coding exon 2) of the SYNPO gene. This alteration results from a G to A substitution at nucleotide position 455, causing the arginine (R) at amino acid position 152 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
