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.131C>T (p.S44F) alteration is located in exon 2 (coding exon 1) of the PHLDB2 gene. This alteration results from a C to T substitution at nucleotide position 131, causing the serine (S) at amino acid position 44 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
