Genes affected

AJAP1 (HGNC:30801): (adherens junctions associated protein 1) Enables beta-catenin binding activity. Involved in negative regulation of cell-matrix adhesion; negative regulation of wound healing; and regulation of polarized epithelial cell differentiation. Located in several cellular components, including adherens junction; basolateral plasma membrane; and cell-cell contact zone. Is spanning component of plasma membrane.

The c.448G>A (p.A150T) alteration is located in exon 2 (coding exon 2) of the AJAP1 gene. This alteration results from a G to A substitution at nucleotide position 448, causing the alanine (A) at amino acid position 150 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
