Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2023The c.2479G>A (p.D827N) alteration is located in exon 13 (coding exon 13) of the ANKRD18A gene. This alteration results from a G to A substitution at nucleotide position 2479, causing the aspartic acid (D) at amino acid position 827 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
