Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.2580T>G (p.S860R) alteration is located in exon 17 (coding exon 16) of the DENND2C gene. This alteration results from a T to G substitution at nucleotide position 2580, causing the serine (S) at amino acid position 860 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
