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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2023The c.22C>A (p.Q8K) alteration is located in exon 1 (coding exon 1) of the ATXN2L gene. This alteration results from a C to A substitution at nucleotide position 22, causing the glutamine (Q) at amino acid position 8 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
