Genes affected

STON2 (HGNC:30652): (stonin 2) This gene encodes a protein which is a membrane protein involved in regulating endocytotic complexes. The protein product is described as one of the clathrin-associated sorting proteins, adaptor molecules which ensure specific proteins are internalized. The encoded protein has also been shown to participate in synaptic vesicle recycling through interaction with synaptotagmin 1 required for neurotransmission. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

The c.2230A>G (p.R744G) alteration is located in exon 4 (coding exon 4) of the STON2 gene. This alteration results from a A to G substitution at nucleotide position 2230, causing the arginine (R) at amino acid position 744 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
