not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2024The c.289C>T (p.R97W) alteration is located in exon 4 (coding exon 4) of the DDX19A gene. This alteration results from a C to T substitution at nucleotide position 289, causing the arginine (R) at amino acid position 97 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
