Genes affected

PHLDB2 (HGNC:29573): (pleckstrin homology like domain family B member 2) Enables cadherin binding activity. Involved in several processes, including negative regulation of focal adhesion assembly; regulation of cytoskeleton organization; and regulation of embryonic development. Located in several cellular components, including basal cortex; cell leading edge; and intermediate filament cytoskeleton. Colocalizes with focal adhesion.

The c.674G>C (p.R225T) alteration is located in exon 2 (coding exon 1) of the PHLDB2 gene. This alteration results from a G to C substitution at nucleotide position 674, causing the arginine (R) at amino acid position 225 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
