Collection Method: clinical testing

The c.94G>C (p.A32P) alteration is located in exon 2 (coding exon 1) of the SERTAD1 gene. This alteration results from a G to C substitution at nucleotide position 94, causing the alanine (A) at amino acid position 32 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
