Hypothesis: association of the critical region of trisomy 18 and 18q2—syndrome with dermatoglyphic findings and a growth suppressor (deleted in colon cancer) locus

Evidence from the literature is reviewed to suggest that when fingertip dermal ridge patterns in chromosomal deletion syndromes are characteristic of the opposite spectrum of the developmental scale from patterns found in cases trisomic for the same chromosomal region, the association may be a consequence of loci with growth regulatory functions. Evidence is presented that DNA markers at 18q21 should be the first candidate sequences to be used to test this hypothesis in families with fingertip arches segregating in an apparent autosomal dominant fashion.     

皮纹与智力相关关系的多因素分析

本文用多因素分析方法，对智商分布于25－121之间的939人的24项指，掌纹性状，结合智商进行相关分析，用逐步回归方法，建立多元线性回归方程，该方程有较好地区分高，中低智力组的区分率（96．49％），回代符合率也远高于理论值，达81．26％，通过该方程所测得皮纹智商与生理智商一致，二者无显著差异，该方程能较好地反映一个人在智力上的遗传素质，并具有简单，方便，易学制，不爱主管观条件影响，测试结果稳定等优点，是便于在广大基层普及推广的一种智力测试方法，对提高我国人口素质具有积极的实用意义。     

142例先天性智能发育不全患儿的遗传学研究

应用细胞遗传学和皮纹分析方法对142例先天性智能发育不全患儿进行了研究。其中,120例正常核型,22例异常核型。异常核型46,XY,t(1;3;21)(1pter→1q32.1∶∶21p11.2→21qter;3 qter→3p26.2∶∶1 q32.1→1 qter)和45,X/45,X,-22,+der(22)t(Y;22)(22qter→22p11.1∶∶Yq11.1→Yq11.2)两种核型国内尚未见报道。皮纹分析结果表明56.7%的患者有1项以上异常皮纹;染色体异常患者均有2项以上异常皮纹;先天愚型患者有“特定”的皮纹改变。     

新疆塔塔尔族肤纹学

目的：本文报道新疆维吾尔自治区塔塔尔族人群的肤纹参数。方法：在知情同意手续下捺印调查对象的手纹和足纹，样本包括29名男性和24名女性。结果：调查的项目有TFRC、a—bRC、atd、tPD、指纹、指间纹、手小鱼际、猿线、大拇趾球纹、趾间纹、足小鱼际纹和足跟纹等。结论：左右同名对应的指纹(足纹)显示同类花纹的组合多于期望值，表明同类花纹有亲和性或相容性。本文为人类学、遗传学和医学提供了较完整的数据集。     

Partial sweat gland aplasia in incontinentia pigmenti Bloch-Sulzberger

Dermatoglyphic investigation of palm prints in patients with Incontinentia pigmenti revealed in five of eight cases a partial ridge dissociation with lack of sweat gland pores. This disease can, therefore, be accepted as a second X-linked anhidrotic ectodermal dysplasia, which, however, is only segregated in the female.     

Dermatoglyphics in Congenital Adrenal Hyperplasia (CAH)

Dermatoglyphic findings were compared in 42 patients (32 females, 10 males) with Congenital Adrenal Hyperplasia (CAH) and 110 normal controls (70 females, 40 males). In CAH males, an excess of whorls (p less than 0.001), an increased total finger ridge count (p less than 0.05), and an increased frequency of patterns in the fourth interdigital area (p less than 0.025) was found. A main line A terminating high in the hypothenar area (p less than 0.05), and a missing c-triradius or an abortive main line C (p less than 0.05) was observed in CAH females. Both sexes displayed an increase in the frequency of small radially directed hypothenar patterns (p less than 0.05) and sydney lines (p less than 0.01).     

Effects of placentation on selected type A behaviors in adult males in the national heart,lung, and blood institute (NHLBI) twin study

A dermatoglyphic index derived from monozygotic (MZ) twins of known placental type was used to estimate placentation retrospectively in a sample of adult male MZ twins. Examination of behavioral test scores with respect to placentation showed that the within-pair difference of most measures of type A behavior was smaller in presumed monochorionic than presumed dichorionic pairs. Measures of cognitive function and hostility were not related to placental type. Intraclass correlations in the monochorionic subgroup of MZ twins were greater than the correlations reported for the full sample of MZ twins. The trends were strongest for the Adjective Check List scales taken at two different exams 5 years apart and, to a lesser extent, for the Framingham type A scale. Our results are most consistent with greater intrauterine environmental covariance in monochorionic MZ twins as an explanation for inflation of the MZ twin correlation relative to dizygotic (DZ) correlation reported for some type A measures.     

Dermatoglyphic peculiarities in patients with Williams-Beuren syndrome

The dermatoglyphic patterns of fingertips and palms of 115 patients with Williams-Beuren syndrome (WBS) were analysed and compared with the data from 199 control individuals from Germany. The following combination of dermatoglyphic patterns appears to be characteristic to WBS: an excess of whorls on all fingertips; high termination values of the main lines D, B, and A; frequent absence of C triradius (C°); high frequencies of ulnar loops on the hypothenar and distal loops on the 2nd, 3rd, and 4th inter digital areas, of distal axial triradii t", and of abnormal palmar creases such as simian crease and Sydney lines. The combination of fingertip and palmar patterns expressed by a “Log.Score-Index,” provides a high degree of discrimination between the WBS patients (92%) and the control group (88%). A “phantom picture” for WBS was constructed, which can be used for its diagnosis. © 1994 Wiley-Liss, Inc.     

A new interstitial deletion of chromosome No. 4 del(4) (q22::q25)

A female child is described with multiple anomalies including epicanthus, frontal bossing, short sternum, polydactyly, cleft of the larynx, renal cysts, and unusual dermatoglyphics. She died aged 3 months and was found to have a unique de novo deletion of chromosome No. 4 (q22-q25). This case is compared with other long arm deletions of 4q and reference made to assignment of genetic markers to chromosome No. 4.
