Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 08, 2023The c.898C>G (p.P300A) alteration is located in exon 10 (coding exon 10) of the DENND6A gene. This alteration results from a C to G substitution at nucleotide position 898, causing the proline (P) at amino acid position 300 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
