Genes affected
SNCAIP (HGNC:11139): (synuclein alpha interacting protein) This gene encodes a protein containing several protein-protein interaction domains, including ankyrin-like repeats, a coiled-coil domain, and an ATP/GTP-binding motif. The encoded protein interacts with alpha-synuclein in neuronal tissue and may play a role in the formation of cytoplasmic inclusions and neurodegeneration. A mutation in this gene has been associated with Parkinson's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 26, 2023The c.1381G>A (p.V461I) alteration is located in exon 7 (coding exon 6) of the SNCAIP gene. This alteration results from a G to A substitution at nucleotide position 1381, causing the valine (V) at amino acid position 461 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
