Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2023The c.2152G>C (p.E718Q) alteration is located in exon 14 (coding exon 13) of the DENND2C gene. This alteration results from a G to C substitution at nucleotide position 2152, causing the glutamic acid (E) at amino acid position 718 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
