Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2023The c.1831G>A (p.D611N) alteration is located in exon 12 (coding exon 11) of the DENND2C gene. This alteration results from a G to A substitution at nucleotide position 1831, causing the aspartic acid (D) at amino acid position 611 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
