摘要:

Acid phosphatases from human saliva have been demonstrated by the zymogram technique. Six phenotypes were found. Family and population studies suggested that the phenotypes are the product of two loci, Sap-A with three alleles A, A’ and O, and Sap-B with two alleles B and

摘要:

Gene frequencies of the esterase D system were estimated in a sample of 1,392 unrelated adults living in Copenhagen; the results were EsD1 = 0.896 and EsD2 = 0.104. No genetic linkage could be demonstrated between this system and a series of autosomal markers.

摘要:

Results on 605 patients and 597 controls carefully matched in relation to sex, age, marital status and profession are reported. A higher frequency of nonsecretors, as well as an excess of B and lack of A2 were observed among the filarial patients. Since these differences do not occur in other series, however, their significance is doubtful.

摘要:

Glucose-6-phosphate dehydrogenase (hexose-6-phosphate dehydrogenase) from human saliva has been demonstrated by the zymogram technique. Three phenotypes were found. Family and population studies suggested that these phenotypes are the products of an autosomal locus with two alleles Sgd-1 and Sgd-2.

摘要:

The Land and Sea Dayaks of Sarawak were surveyed for several erythrocyte enzymes. The gene frequency of 6PGDC in 132 Land Dayaks and 127 Sea Dayaks were 0.045 and 0.047, respectively. The gene frequency of PGM11 in 285 Land Dayks and 240 Sea Dayaks were 0.716 and 0.779, respectively. The ADA2 gene frequency in 283 Land Dayaks and 188 Sea Dayaks were 0.154 and 0.090. ADA 5–1 was found once in the Land Dayaks and once in the Sea Dayaks. AK 2–1 was found once in 221 Sea Dayaks but not in any of 270 Land Dayaks. No PHI, LDH or CA variants were found among the Land or Sea Day

摘要:

Pseudocholinesterase was examined in 322 samples from unrelated, healthy blood donors. In 14 cases heterozygosity was found, i.e. the frequency of the allele for atypical cholinesterase amounts to 0.022. A comparison is made with other European populations.

摘要:

A statewide survey of four endogamous Brahman populations of Tamil Nadu reveals a low level of inbreeding in three of them. In the fourth population, the Thengalai, the level is higher, but not as high as in other social castes. The Tamil Brahmans rank next to the Telugu and the Kanarese Brahmans in this respect. Uncle-niece marriages also occur as in Telugu-speaking populations, and these exceed in the two Ayyangar populations in comparison to the Ayyar. A decline of first-cousin marriages and an increase of uncle-niece marriages are detected in the first two living generations in each population.

摘要:

The heritable falciform folds and congenital retinal non-attachment reported in the literature are here divided into monosymptomatic and complex types. Of the former, autosomal dominant and recessive disorders are known. The complex types comprise several syndromes, both autosomal recessive and X-linked. Retinal dysplasia is sometimes seen in histological sections from these affections, but it is an unspecific histological reaction, and not a disease sui generis. Attention is drawn to the syndrome with microcephaly, microphthalmia and falciform detachment which, though previously described, has not so far been delineated. It is hypothesized that hydrocephaly and congenital retinal non-attachment with or without microphfhalmia and persistent hyperplastic primary vitreous constitute yet another ‘new’ syndrome, mainly seen in fema
