Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 26, 2023The c.359A>T (p.N120I) alteration is located in exon 5 (coding exon 5) of the DDX19A gene. This alteration results from a A to T substitution at nucleotide position 359, causing the asparagine (N) at amino acid position 120 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
