The c.2732T>C (p.L911S) alteration is located in exon 20 (coding exon 20) of the SCAF8 gene. This alteration results from a T to C substitution at nucleotide position 2732, causing the leucine (L) at amino acid position 911 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
