Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.1027G>A (p.D343N) alteration is located in exon 8 (coding exon 8) of the AMDHD2 gene. This alteration results from a G to A substitution at nucleotide position 1027, causing the aspartic acid (D) at amino acid position 343 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
