Genes affected
RBFOX1 (HGNC:18222): (RNA binding fox-1 homolog 1) The Fox-1 family of RNA-binding proteins is evolutionarily conserved, and regulates tissue-specific alternative splicing in metazoa. Fox-1 recognizes a (U)GCAUG stretch in regulated exons or in flanking introns. The protein binds to the C-terminus of ataxin-2 and may contribute to the restricted pathology of spinocerebellar ataxia type 2 (SCA2). Ataxin-2 is the product of the SCA2 gene which causes familial neurodegenerative diseases. Fox-1 and ataxin-2 are both localized in the trans-Golgi network. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

Uncertain significance, criteria provided, single submitterclinical testingInvitaeSep 25, 2023In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RBFOX1 protein function. ClinVar contains an entry for this variant (Variation ID: 529521). This variant has not been reported in the literature in individuals affected with RBFOX1-related conditions. This variant is present in population databases (rs373077021, gnomAD 0.007%). This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 118 of the RBFOX1 protein (p.Thr118Met). -
