Genes affected
ATXN3L (HGNC:24173): (ataxin 3 like) This intronless gene may be a pseudogene (PMID:11450850). This gene is similar to the multi-exon gene which encodes ataxin 3 and contains a coding region which could encode a protein similar to ataxin 3. Mutations in the gene encoding ataxin 3 are associated with Machado-Joseph disease. [provided by RefSeq, Sep 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.835C>T (p.P279S) alteration is located in exon 1 (coding exon 1) of the ATXN3L gene. This alteration results from a C to T substitution at nucleotide position 835, causing the proline (P) at amino acid position 279 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
