Genes affected

ATXN2L (HGNC:31326): (ataxin 2 like) This gene encodes an ataxin type 2 related protein of unknown function. This protein is a member of the spinocerebellar ataxia (SCAs) family, which is associated with a complex group of neurodegenerative disorders. Several alternatively spliced transcripts encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.28C>T (p.P10S) alteration is located in exon 1 (coding exon 1) of the ATXN2L gene. This alteration results from a C to T substitution at nucleotide position 28, causing the proline (P) at amino acid position 10 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
