Pik3ap1^M3Btlr

ENU-induced T to C transition at base pair 41,376,146 (v38) on chromosome 19, or base pair 8,925 in the GenBank genomic region NC_000085 encoding Pik3ap1. The mutation corresponds to residue 303 in the NM_031376.3 mRNA sequence in exon 2 of 17 total exons. The mutation results in a tyrosine to histidine substitution at position 45 (Y45H) in the B cell adaptor protein (BCAP) protein. (J:272019)
