Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 05, 2022The c.1729C>T (p.P577S) alteration is located in exon 11 (coding exon 10) of the DENND2C gene. This alteration results from a C to T substitution at nucleotide position 1729, causing the proline (P) at amino acid position 577 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
