Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.416T>C (p.F139S) alteration is located in exon 5 (coding exon 4) of the DENND3 gene. This alteration results from a T to C substitution at nucleotide position 416, causing the phenylalanine (F) at amino acid position 139 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
