Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.509A>G (p.D170G) alteration is located in exon 5 (coding exon 5) of the ARPIN gene. This alteration results from a A to G substitution at nucleotide position 509, causing the aspartic acid (D) at amino acid position 170 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
