Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 25, 2024The c.3308G>A (p.R1103H) alteration is located in exon 20 (coding exon 19) of the DENND4B gene. This alteration results from a G to A substitution at nucleotide position 3308, causing the arginine (R) at amino acid position 1103 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
