Genes affected

PODXL (HGNC:9171): (podocalyxin like) This gene encodes a member of the sialomucin protein family. The encoded protein was originally identified as an important component of glomerular podocytes. Podocytes are highly differentiated epithelial cells with interdigitating foot processes covering the outer aspect of the glomerular basement membrane. Other biological activities of the encoded protein include: binding in a membrane protein complex with Na+/H+ exchanger regulatory factor to intracellular cytoskeletal elements, playing a role in hematopoetic cell differentiation, and being expressed in vascular endothelium cells and binding to L-selectin.

The c.1484G>A (p.R495Q) alteration is located in exon 9 (coding exon 9) of the PODXL gene. This alteration results from a G to A substitution at nucleotide position 1484, causing the arginine (R) at amino acid position 495 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
