Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.430A>T (p.T144S) alteration is located in exon 6 (coding exon 6) of the DDX19A gene. This alteration results from a A to T substitution at nucleotide position 430, causing the threonine (T) at amino acid position 144 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
