Genes affected

PDPN (HGNC:29602): (podoplanin) This gene encodes a type-I integral membrane glycoprotein with diverse distribution in human tissues. The physiological function of this protein may be related to its mucin-type character. The homologous protein in other species has been described as a differentiation antigen and influenza-virus receptor. The specific function of this protein has not been determined but it has been proposed as a marker of lung injury. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

Dec 19, 2022

The c.68C>G (p.A23G) alteration is located in exon 1 (coding exon 1) of the PDPN gene. This alteration results from a C to G substitution at nucleotide position 68, causing the alanine (A) at amino acid position 23 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
