Prospective cytomegalovirus surveillance in paediatric renal transplant patients.

Fifty-eight consecutive paediatric recipients of 65 renal transplants were prospectively studied for up to 72 months for evidence of cytomegalovirus (CMV) infection. Blood, urine and saliva were screened for CMV pre transplant and then weekly for the first 6 weeks, and monthly thereafter, by conventional cell culture and by detection of early antigen fluorescent foci. Donor CMV serostatus was available in 51 cases.

Microcephaly, focal segmental glomerulonephritis and marfanoid habitus in two sibs.

Two female sibs aged 15 and 18 years with microcephaly, mental retardation and marfanoid habitus who developed focal segmental glomerulonephritis leading to renal failure are described. This combination of features appears to represent a unique syndrome distinct from previous reports of microcephaly in association with the nephrotic syndrome. The mode of inheritance is likely to be autosomal recessive.

Identification of a single missense mutation in the adenine phosphoribosyltransferase (APRT) gene from five Icelandic patients and a British patient.

We have completely sequenced the adenine phosphoribosyltransferase (APRT) gene from each of six patients--five (I-V) from Iceland and one (VI) from Britain. Cases I and II shared a common ancestor six and seven generations ago, and cases I and V shared a common ancestor seven generations ago, but cases III and IV were unrelated to the above or to each other, over seven generations. Genomic DNA was amplified by PCR, subcloned into M13mp18, and sequenced.
