Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.1582G>A (p.D528N) alteration is located in exon 17 (coding exon 17) of the TTC39A gene. This alteration results from a G to A substitution at nucleotide position 1582, causing the aspartic acid (D) at amino acid position 528 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
