Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.220G>A (p.D74N) alteration is located in exon 5 (coding exon 3) of the APBB1IP gene. This alteration results from a G to A substitution at nucleotide position 220, causing the aspartic acid (D) at amino acid position 74 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
