Genes affected

FSTL1 (HGNC:3972): (follistatin like 1) This gene encodes a protein with similarity to follistatin, an activin-binding protein. It contains an FS module, a follistatin-like sequence containing 10 conserved cysteine residues. This gene product is thought to be an autoantigen associated with rheumatoid arthritis.

The c.797C>T (p.T266I) alteration is located in exon 9 (coding exon 8) of the FSTL1 gene. This alteration results from a C to T substitution at nucleotide position 797, causing the threonine (T) at amino acid position 266 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
