The c.3201G>T (p.W1067C) alteration is located in exon 11 (coding exon 10) of the SCAF11 gene. This alteration results from a G to T substitution at nucleotide position 3201, causing the tryptophan (W) at amino acid position 1067 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
