The c.15781A>G (p.T5261A) alteration is located in exon 94 (coding exon 94) of the MDN1 gene. This alteration results from a A to G substitution at nucleotide position 15781, causing the threonine (T) at amino acid position 5261 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
