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]

Ambry Genetics

Jun 05, 2023

The c.190A>T (p.T64S) alteration is located in exon 4 (coding exon 3) of the SNCAIP gene. This alteration results from a A to T substitution at nucleotide position 190, causing the threonine (T) at amino acid position 64 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
