Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2024The c.1388C>T (p.T463I) alteration is located in exon 14 (coding exon 12) of the APBB1IP gene. This alteration results from a C to T substitution at nucleotide position 1388, causing the threonine (T) at amino acid position 463 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
