The c.16741G>A (p.D5581N) alteration is located in exon 102 (coding exon 102) of the MDN1 gene. This alteration results from a G to A substitution at nucleotide position 16741, causing the aspartic acid (D) at amino acid position 5581 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
