The c.3199C>T (p.R1067C) alteration is located in exon 20 (coding exon 19) of the IGSF22 gene. This alteration results from a C to T substitution at nucleotide position 3199, causing the arginine (R) 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. -
