The c.832C>T (p.P278S) alteration is located in exon 2 (coding exon 2) of the MAML3 gene. This alteration results from a C to T substitution at nucleotide position 832, causing the proline (P) at amino acid position 278 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
