Jul 30, 2023

The c.21C>A (p.S7R) alteration is located in exon 1 (coding exon 1) of the IGSF6 gene. This alteration results from a C to A substitution at nucleotide position 21, causing the serine (S) at amino acid position 7 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
