Dec 06, 2021

The c.68C>G (p.S23C) alteration is located in exon 1 (coding exon 1) of the SPIRE2 gene. This alteration results from a C to G substitution at nucleotide position 68, causing the serine (S) at amino acid position 23 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
