Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.232C>A (p.Q78K) alteration is located in exon 2 (coding exon 2) of the DENND2D gene. This alteration results from a C to A substitution at nucleotide position 232, causing the glutamine (Q) at amino acid position 78 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
