Feb 05, 2024

The c.32G>A (p.S11N) alteration is located in exon 1 (coding exon 1) of the SPON1 gene. This alteration results from a G to A substitution at nucleotide position 32, causing the serine (S) at amino acid position 11 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
