The c.887C>T (p.S296F) alteration is located in exon 9 (coding exon 8) of the SIGIRR gene. This alteration results from a C to T substitution at nucleotide position 887, causing the serine (S) at amino acid position 296 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
