Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.920A>C (p.D307A) alteration is located in exon 8 (coding exon 7) of the DENND3 gene. This alteration results from a A to C substitution at nucleotide position 920, causing the aspartic acid (D) at amino acid position 307 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
