The c.184A>C (p.T62P) alteration is located in exon 1 (coding exon 1) of the NECAB2 gene. This alteration results from a A to C substitution at nucleotide position 184, causing the threonine (T) at amino acid position 62 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
