Genes affected

FXR1 (HGNC:4023): (FMR1 autosomal homolog 1) The protein encoded by this gene is an RNA binding protein that interacts with the functionally-similar proteins FMR1 and FXR2. These proteins shuttle between the nucleus and cytoplasm and associate with polyribosomes, predominantly with the 60S ribosomal subunit. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.575T>C (p.I192T) alteration is located in exon 7 (coding exon 7) of the FXR1 gene. This alteration results from a T to C substitution at nucleotide position 575, causing the isoleucine (I) at amino acid position 192 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
