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.1564A>G (p.M522V) alteration is located in exon 9 (coding exon 9) of the PODXL gene. This alteration results from a A to G substitution at nucleotide position 1564, causing the methionine (M) at amino acid position 522 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). This variant has not been reported in the literature in individuals affected with PODXL-related conditions. This variant is present in population databases (rs138022509, gnomAD 0.003%). This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 490 of the PODXL protein (p.Met490Val). -
