The c.259C>T (p.P87S) alteration is located in exon 3 (coding exon 3) of the TMED8 gene. This alteration results from a C to T substitution at nucleotide position 259, causing the proline (P) at amino acid position 87 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
