The c.188A>C (p.Y63S) alteration is located in exon 2 (coding exon 2) of the MSTO1 gene. This alteration results from an A to C substitution at nucleotide position 188, causing the tyrosine (Y) at amino acid position 63 to be replaced by a serine (S). Based on data from the Genome Aggregation Database (gnomAD), the MSTO1 c.188A>C alteration was not observed. This amino acid position is highly conserved in available vertebrate species. The in silico prediction for the p.Y63S alteration is inconclusive. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
