Mutation
description
Allele Type:    Spontaneous
Mutation:    Intragenic deletion
 
Mutation detailsA 2 base "TA" deletion at positions 62 and 63 of an 83 base pair exon near the 5' end of the gene is found in the following mouse strains: A/HeJ, A/J, AKR/J, DBA/2J, I/LnJ, KK/HlJ, MOLF/EiJ, NZB/B1NJ, RF/J, ST/bJ SWR/J, B10.D2/oSnJ. The consequence of this deletion is the creation of a stop codon starting four bases after the deletion. A truncated product of 216 amino acids is predicted as a result although contradictory reports exist that a larger pro-C5 protein may be synthesized. Nevertheless, macrophages from mouse strains carrying this allele do not secrete complement 5. (J:5016, J:23983, J:262923)

Notes

This is an allele characteristic of various inbred mouse strains including the following: A/HeJ, A/J, AKR/J, DBA/2J, NZB/B1NJ, SWR/J, B10.D2/oSnJ

Hc was identified as a candidate gene for Abhr2 in a microarray analysis of lung mRNA from A/J, C3H/HeJ, and (A/J x C3H/HeJ)F1 x A/J backcross animals. Hc genotype shows statistically significant correlation to allergen-induced bronchial hyperresponsive phenotype. The A/J allele contains a 2 bp deletion resulting in deficient Hc mRNA and protein production and is associated with susceptibility to allergen-induced bronchial hyperresponsiveness. (J:108211)
