Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2024The c.896C>T (p.T299M) alteration is located in exon 8 (coding exon 7) of the DENND3 gene. This alteration results from a C to T substitution at nucleotide position 896, causing the threonine (T) at amino acid position 299 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
