The c.481C>T (p.P161S) alteration is located in exon 4 (coding exon 4) of the FCRL6 gene. This alteration results from a C to T substitution at nucleotide position 481, causing the proline (P) at amino acid position 161 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
