Bleeding disorder, platelet-type, 8; BDPLT8

Disease ID:760
Name:Bleeding disorder, platelet-type, 8; BDPLT8
Associated with:1 target
P2Y12 defect
Database Links
OMIM: 609821
Orphanet: ORPHA36355


P2Y12 receptor
Comments:  In a patient with congenital bleeding, heterozygosity for 2 mutations in the P2Y12 gene was found. Analysis of the patient's P2Y12 gene revealed a G-to-A transition in one allele, changing the codon for Arg-256 in the sixth transmembrane domain to Gln, and a C-to-T transition in the other allele, changing the codon for Arg-265 in the third extracellular loop to Trp. These patients generally have normal shape change responses to ADP but have impaired abilities to inhibit adenylate cyclase activity.
