Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 20, 2023 | The c.3067A>G (p.R1023G) alteration is located in exon 16 (coding exon 16) of the DENND5B gene. This alteration results from a A to G substitution at nucleotide position 3067, causing the arginine (R) at amino acid position 1023 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
