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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 13, 2021The c.634C>T (p.R212W) alteration is located in exon 2 (coding exon 2) of the AJAP1 gene. This alteration results from a C to T substitution at nucleotide position 634, causing the arginine (R) at amino acid position 212 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
