The c.782C>T (p.A261V) alteration is located in exon 6 (coding exon 6) of the FCAMR gene. This alteration results from a C to T substitution at nucleotide position 782, causing the alanine (A) at amino acid position 261 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
