not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 07, 2023The c.746G>A (p.R249Q) alteration is located in exon 8 (coding exon 8) of the DBNL gene. This alteration results from a G to A substitution at nucleotide position 746, causing the arginine (R) at amino acid position 249 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
