Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.121G>A (p.A41T) alteration is located in exon 4 (coding exon 2) of the APBB1IP gene. This alteration results from a G to A substitution at nucleotide position 121, causing the alanine (A) at amino acid position 41 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
