The c.2060C>A (p.S687Y) alteration is located in exon 13 (coding exon 13) of the MPHOSPH9 gene. This alteration results from a C to A substitution at nucleotide position 2060, causing the serine (S) at amino acid position 687 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
