The c.993G>C (p.Q331H) alteration is located in exon 8 (coding exon 7) of the FSTL5 gene. This alteration results from a G to C substitution at nucleotide position 993, causing the glutamine (Q) at amino acid position 331 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
