The c.16721C>T (p.A5574V) alteration is located in exon 102 (coding exon 102) of the MDN1 gene. This alteration results from a C to T substitution at nucleotide position 16721, causing the alanine (A) at amino acid position 5574 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
