Collection Method: clinical testing

The c.310T>C (p.S104P) alteration is located in exon 2 (coding exon 2) of the CMYA5 gene. This alteration results from a T to C substitution at nucleotide position 310, causing the serine (S) at amino acid position 104 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
