Spontaneous Allele Detail
Symbol: Pla2g2aMom1-s
Name: phospholipase A2, group IIA (platelets, synovial fluid); modifier of Min1, tumor susceptibility
MGI ID: MGI:1857821
Synonyms: IIA sPLA2, Mom-1, sPLA2 IIa, sPLA2-IIA-
Gene: Pla2g2a  Location: Chr4:138831857-138835186 bp, + strand  Genetic Position: Chr4, 70.57 cM
Strain of Origin:  C57BL/6J
Allele Type:    Spontaneous
Mutation:    Insertion
Mutation detailsInsertion of thymidine at position 208 (position 166 from the ATG) results in a frameshift that creates a stop codon 13 amino acids downstream in exon 4. The mutation causes the loss of a BamHI restriction site and a defective protein. (J:26137, J:28799)
Inheritance:    Dominant

Carrying any Pla2g2a Mutation:  7 strains or lines available
129 substrains, C57BL/6J and BTBR carry this inbred strain variant allele.

A mutation in the Apc gene of the mouse causes multiple intestinal adenomas in the C57BL/6J strain on which it arose. In crosses with other strains, the number of tumors is reduced. A locus controlling about 50% of genetic variation in tumor number has been identified as Pla2g2a.
