| Remarks |
Deceased at age 25 days; cardiomegaly; hepatosplenomegaly; nephromegaly; hypertension at birth; extensive mineralization of walls of elastic arteries, polyhydramnios & fetal macrosomia; sev atherosclerosis; congestive heart failure; donor subject is a compound heterozygote: one allele carries a T>G transversion at nucleotide 936 (936T>G) in exon 9 of the ENPP1 gene, which results in a nonsense mutation at codon 312 [TYR312TER (Y312X)]; the second allele carries an A>G transition at nucleotide 2375 (2375A>G) in exon 23, which results in a missense mutation at codon 792 [ASN792SER (N792S)]. |
