Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 28, 2022The c.766T>C (p.C256R) alteration is located in exon 9 (coding exon 9) of the DBNL gene. This alteration results from a T to C substitution at nucleotide position 766, causing the cysteine (C) at amino acid position 256 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
