Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2024The c.472T>A (p.S158T) alteration is located in exon 6 (coding exon 6) of the DDX19A gene. This alteration results from a T to A substitution at nucleotide position 472, causing the serine (S) at amino acid position 158 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
