Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.1873A>G (p.I625V) alteration is located in exon 12 (coding exon 11) of the DENND2C gene. This alteration results from a A to G substitution at nucleotide position 1873, causing the isoleucine (I) at amino acid position 625 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
