Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2024The c.250A>C (p.N84H) alteration is located in exon 4 (coding exon 4) of the DDX19A gene. This alteration results from a A to C substitution at nucleotide position 250, causing the asparagine (N) at amino acid position 84 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
