Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 30, 2024The c.1186C>T (p.R396W) alteration is located in exon 11 (coding exon 11) of the DENND2D gene. This alteration results from a C to T substitution at nucleotide position 1186, causing the arginine (R) at amino acid position 396 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
