The c.551A>C (p.N184T) alteration is located in exon 2 (coding exon 2) of the MAML3 gene. This alteration results from a A to C substitution at nucleotide position 551, causing the asparagine (N) at amino acid position 184 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
