Genes affected

ATXN10 (HGNC:10549): (ataxin 10) This gene encodes a protein that may function in neuron survival, neuron differentiation, and neuritogenesis. These roles may be carried out via activation of the mitogen-activated protein kinase cascade. Expansion of an ATTCT repeat from 9-32 copies to 800-4500 copies in an intronic region of this locus has been associated with spinocerebellar ataxia, type 10. Alternatively spliced transcript variants have been described.[provided by RefSeq, Jul 2016]

The c.647+2dupT intronic alteration consists of a duplication of T two nucleotides after exon 5 of the ATXN10 gene. Alterations that disrupt the canonical splice donor site are typically deleterious in nature (Richards, 2015). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
