Genes affected
APBA3 (HGNC:580): (amyloid beta precursor protein binding family A member 3) The protein encoded by this gene is a member of the X11 protein family. It is an adapter protein that interacts with the Alzheimer's disease amyloid precursor protein. This gene product is believed to be involved in signal transduction processes. This gene is a candidate gene for Alzheimer's disease. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1598G>C (p.S533T) alteration is located in exon 10 (coding exon 9) of the APBA3 gene. This alteration results from a G to C substitution at nucleotide position 1598, causing the serine (S) at amino acid position 533 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
