Genes affected

DPP10 (HGNC:20823): (dipeptidyl peptidase like 10) This gene encodes a single-pass type II membrane protein that is a member of the S9B family in clan SC of the serine proteases. This protein has no detectable protease activity, most likely due to the absence of the conserved serine residue normally present in the catalytic domain of serine proteases. However, it does bind specific voltage-gated potassium channels and alters their expression and biophysical properties. Mutations in this gene have been associated with asthma. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

The c.203C>T (p.S68L) alteration is located in exon 3 (coding exon 3) of the DPP10 gene. This alteration results from a C to T substitution at nucleotide position 203, causing the serine (S) at amino acid position 68 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
