not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 22, 2024The c.302G>A (p.R101Q) alteration is located in exon 3 (coding exon 3) of the DBF4 gene. This alteration results from a G to A substitution at nucleotide position 302, causing the arginine (R) at amino acid position 101 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
