Genes affected
BTBD9 (HGNC:21228): (BTB domain containing 9) This locus encodes a BTB/POZ domain-containing protein. This domain is known to be involved in protein-protein interactions. Polymorphisms at this locus have been reported to be associated with susceptibility to Restless Legs Syndrome and may also be associated with Tourette Syndrome. Alternatively spliced transcript variants have been described. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2023The c.1288A>G (p.I430V) alteration is located in exon 9 (coding exon 7) of the BTBD9 gene. This alteration results from a A to G substitution at nucleotide position 1288, causing the isoleucine (I) at amino acid position 430 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
