Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.373G>A (p.D125N) alteration is located in exon 3 (coding exon 3) of the PDZD9 gene. This alteration results from a G to A substitution at nucleotide position 373, causing the aspartic acid (D) at amino acid position 125 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
