Hereditary peculiarities in individual responses to environmental chemicals are a common occurrence in human populations. Genetic variation in glutathione S-transferase, CYP1A2, N-acetyltransferase, and paraoxonase exemplify the relationship of metabolic variation to individual susceptibility to cancer and other toxicants of environmental origin. Heritable receptor protein variants, a subset of proteins of enormous pharmacogenetic potential that have not thus far been extensively explored from the pharmacogenetic standpoint, are also considered. Examples of interest that are considered include receptor variants associated with retinoic acid resistance in acute promyelocytic leukemia, with paradoxical responses to antiandrogens in prostate cancer, and with retinitis pigmentosa. Additional heritable protein variants of pharmacogenetic interest that result in antibiotic-induced deafness, glucocorticoid-remediable aldosteronism and hypertension, the long-QT syndrome, and beryllium-induced lung disease are also discussed. These traits demonstrate how knowledge of the molecular basis and mechanism of the variant response may contribute to its prevention in sensitive persons as well as to improved therapy for genetically conditioned disorders that arise from environmental chemicals.

We report a 55-year-old man with papilledema and multiple cranial nerve palsies. He was well until 52 years of age when there was an onset of progressive difficulty in initiating urination; he visited the urology service of our hospital where a diagnosis of prostate cancer was made; the cancer was invading the bladder and was metastasizing to lymph nodes and bones. He was treated with oochiectomy and estrogen preparations with some improvement in his symptoms. Two years later, he developed difficulty in urination again, and transurethral resection of the tumor was performed in 1991. In December 1991, he noted tingling and numb sensation in his left face, which had become progressive worse within the next one month, and he developed blepharoptosis and deafness all on the left side. He was admitted to the urology service on February 4, 1992, and a neurological consultation was asked. On physical examination, general findings were unremarkable, except for lymph node enlargements of about 0.5 to 1.0 mm in size in cervical and inguinal regions. On neurologic examination, he was alert with normal mental activities; higher cerebral functions were intact. He had normal vision and visual fields, however, papilledema was present bilaterally; pupils and light reactions were normal. Extraocular muscles were intact on the right side, however, moderate restriction was noted in the left eye in that all the extraocular muscles except for the medial rectus were weak; blepharoptosis was noted on the left; no nystagmus was present. The sensation was diminished in the left face, and left facial paresis of the peripheral type was also noted; the taste sensation was also diminished in the left anterior two thirds of the tongue. He had sensorineural deafness on the left side. The other cranial nerves appeared intact. He walked normally; no weakness or muscle atrophy was noted; muscle tone was normal and no ataxia was observed. Deep reflexes were normally elicited and symmetric; the plantar response was flexor. No meningeal signs were present. Laboratory examination revealed following abnormalities: Hb 7.1 g/dl, platelet 47,000/cmm, WBC3,800/cmm, LDH 950IU/l, PAP232ng/ml (normal less than 1.6), PA2.631ng/ml (normal less than 7.4); a small amount of effusion was noted in the left pleural cavity; cytological examination of the fluid was class V. A cranial CT scan as well as MRI were entirely normal, as was the spinal tap. He was treated with glycerol, however, there was progressive increase in the pleural effusion, and he developed dyspnea; moist rale had become audible in the end of February.(ABSTRACT TRUNCATED AT 400 WORDS)

Human Xq27 contains candidate regions for several disorders, yet is predicted to be a gene-poor cytogenetic band. We have developed a transcription map for the entire cytogenetic band to facilitate the identification of the relatively small number of expected candidate genes. Two approaches were taken to identify genes: (1) a group of 64 unique STSs that were generated during the physical mapping of the region were used in RT-PCR with RNA from human adult and fetal brain and (2) ESTs that have been broadly mapped to this region of the chromosome were finely mapped using a high-resolution yeast artificial chromosome contig. This combined approach identified four distinct regions of transcriptional activity within the Xq27 band. Among them is a region at the centromeric boundary that contains candidate regions for several rare developmental disorders (X-linked recessive hypoparathyroidism, thoracoabdominal syndrome, albinism-deafness syndrome, and Borjeson-Forssman-Lehman syndrome). Two transcriptionally active regions were identified in the center of Xq27 and include candidate regions for X-linked mental retardation syndrome 6, X-linked progressive cone dystrophy, X-linked retinitis pigmentosa 24, and a prostate cancer susceptibility locus. The fourth region of transcriptional activity encompasses the FMR1 (FRAXA) and FMR2 (FRAXE) genes. The analysis thus suggests clustered transcription in Xq27 and provides candidates for several heritable disorders for which the causative genes have not yet been found.

Human cytomegalovirus is a common virus that establishes latency and persistence after a primary infection in 50-90% of populations worldwide. In otherwise healthy persons, the infection is generally mild or asymptomatic, although it may cause mononucleosis, prolonged episodes of fever, and hepatitis. However, in AIDS patients and transplant recipients who are immunosuppressed, severe, life-threatening infections may develop. CMV is also the most common congenital infection and may cause birth defects and deafness. Emerging evidence shows a high prevalence of this virus in patients with chronic inflammatory diseases or tumours of different origin, such as breast, colon, and prostate cancer, neuroblastoma, medulloblastoma, and glioblastoma. Several drugs are available to treat CMV infections. This review will highlight the possibility of using anti-CMV therapy to improve outcome not only in patients with acute CMV infections but also in patients with inflammatory diseases and cancer.
