Deletion of 2 nucleotides (130-131) and two nucleotide substitutions in PGRP-SD; this induces a frameshift, causing a premature stop codon and leading to a peptide of 50 residues lacking the PGRP domain.

Deletion of 4 bases and substitution of 2 bases at the 5' end of PGRP-SD causes a frameshift and early translation termination.
