not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.770C>T (p.A257V) alteration is located in exon 9 (coding exon 9) of the DBNL gene. This alteration results from a C to T substitution at nucleotide position 770, causing the alanine (A) at amino acid position 257 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
