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]

The c.259C>T (p.P87S) alteration is located in exon 2 (coding exon 2) of the RBFOX1 gene. This alteration results from a C to T substitution at nucleotide position 259, causing the proline (P) at amino acid position 87 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 87 of the RBFOX1 protein (p.Pro87Ser). This variant is present in population databases (rs143573994, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with RBFOX1-related conditions. ClinVar contains an entry for this variant (Variation ID: 241956). 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 with a negative predictive value of 80%. In 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. -
