Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.649G>A (p.D217N) alteration is located in exon 5 (coding exon 5) of the ARPIN gene. This alteration results from a G to A substitution at nucleotide position 649, causing the aspartic acid (D) at amino acid position 217 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
