The c.1883C>A (p.T628K) alteration is located in exon 16 (coding exon 15) of the FSTL4 gene. This alteration results from a C to A substitution at nucleotide position 1883, causing the threonine (T) at amino acid position 628 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
