The c.2455C>T (p.P819S) alteration is located in exon 19 (coding exon 18) of the SEMA6A gene. This alteration results from a C to T substitution at nucleotide position 2455, causing the proline (P) at amino acid position 819 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
