Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.16720G>A (p.A5574T) 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 16720, causing the alanine (A) at amino acid position 5574 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
