Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2023The c.1183C>T (p.P395S) alteration is located in exon 10 (coding exon 9) of the DENND3 gene. This alteration results from a C to T substitution at nucleotide position 1183, causing the proline (P) at amino acid position 395 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
