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]

ATXN10 Gene-Disease associations (from GenCC):

• spinocerebellar ataxia type 10

  Inheritance: AD Classification: STRONG, SUPPORTIVE Submitted by: Orphanet, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.279 is higher than 0.05.
