The c.161C>T (p.A54V) alteration is located in exon 1 (coding exon 1) of the CNNM3 gene. This alteration results from a C to T substitution at nucleotide position 161, causing the alanine (A) at amino acid position 54 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
