Genes affected

APLP1 (HGNC:597): (amyloid beta precursor like protein 1) This gene encodes a member of the highly conserved amyloid precursor protein gene family. The encoded protein is a membrane-associated glycoprotein that is cleaved by secretases in a manner similar to amyloid beta A4 precursor protein cleavage. This cleavage liberates an intracellular cytoplasmic fragment that may act as a transcriptional activator. The encoded protein may also play a role in synaptic maturation during cortical development. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

The c.1097C>G (p.S366C) alteration is located in exon 9 (coding exon 9) of the APLP1 gene. This alteration results from a C to G substitution at nucleotide position 1097, causing the serine (S) at amino acid position 366 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
