The c.1544C>T (p.S515F) 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 1544, causing the serine (S) at amino acid position 515 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
