In 1970,1 1971,2 and 19743 we described two families, each with two siblings who had atresia of the first portion of the duodenum. The four patients were first cousins to each other. We suggested a genetic etiology with an autosomal recessive mode of inheritance, which has been accepted.4 The source of the proposed gene for both families was traced to a single individual. Recently, a third family, linked to the previous two with strong consanguineous ties, had a pair of twins affected with the same anomaly. The purpose of this article is to bring the weight of new evidence afforded by this third family to further substantiate the genetic etiology of this condition.

BackgroundThe genetic causes of human idiopathic non-obstructive azoospermia (NOA) with meiotic arrest remain unclear.MethodsTwo Chinese families with infertility participated in the study. In family 1, two brothers were affected by idiopathic NOA. In family 2, the proband was diagnosed with idiopathic NOA, and his elder sister suffered from infertility. Whole-exome sequencing (WES) was conducted in the two patients in family 1, the proband in family 2 and 362 additional sporadic patients with idiopathic NOA. Sanger sequencing was used to verify the WES results. Periodic acid–Schiff (PAS), immunohistochemistry (IHC) and meiotic chromosomal spread analyses were carried out to evaluate the stage of spermatogenesis arrested in the affected cases.ResultsWe identified compound heterozygous loss of function (LoF) variants of SHOC1 (c.C1582T:p.R528X and c.231_232del:p.L78Sfs*9, respectively) in both affected cases with NOA from family 1. In family 2, homozygous LoF variant in SHOC1 (c.1194delA:p.L400Cfs*7) was identified in the siblings with infertility. PAS, IHC and meiotic chromosomal spread analyses demonstrated that the spermatogenesis was arrested at zygotene stage in the three patients with NOA. Consistent with the autosomal recessive mode of inheritance, all of these SHOC1 variants were inherited from heterozygous parental carriers. Intriguingly, WES of 362 sporadic NOA cases revealed one additional NOA case with a bi-allelic SHOC1 LoF variant (c.1464delT:p.D489Tfs*13).ConclusionTo the best of our knowledge, this is the first report identifying SHOC1 as the causative gene for human NOA. Furthermore, our study showed an autosomal recessive mode of inheritance in the NOA caused by SHOC1 deficiency.

SummaryThree cases of hereditary myoclonic epilepsy have been observed among ten siblings in a Negro family. Electroencephalograms of the parents, three normal siblings and two of the three affected siblings have been recorded and all show abnormalities of a similar type. These are of a generalized nature revealing no focal damage. This type of abnormality has been observed in an affected male and two normal siblings by Watson and Denny-Brown.The autosomal recessive mode of inheritance observed in the present study is consistent with the transmission most frequently reported in myoclonic epilepsy. We believe that abnormal electroencephalographic patterns are associated with this gene and that these patterns may be useful in the detection of heterozygous carriers.

Objectives: The aim of this work was to study the pattern of inheritance of celiac disease in a group of Saudi patients and to compare oral mucosal and dental clinical findings in these patients to those of healthy controls.Study design: Fifty patients suffering from celiac disease were screened for dental evaluation. They were subjected to clinical genetic examination, pedigree construction, oral mucosal and dental clinical evaluation. Results: An autosomal recessive mode of inheritance was evident in some of the studied cases,while others showed sporadic occurrence. Oral mucosal and dental clinical examinations revealed recurrent oral ulcerations, enamel hypoplasia in most of the celiac disease patients. Conclusions: Pedigree analysis of families is important to identify the mode of inheritance. Oral mucosal and dental clinical examinations are important in diagnosing and monitoring cases of celiac disease.

Mode Of Inheritance

 Split-hand/split-foot malformation (SHFM), also known as ectrodactyly or lobster claw hand is a congenital limb malformation, characterized by a deep median cleft of the hand and/or foot due to the absence of the central rays of the autopod. It may occur singly or in association with syndromes, former being mostly autosomal dominant but autosomal recessive variety is rare. We are reporting a case of ectrodactyly with autosomal recessive mode of inheritance DOI: http://dx.doi.org/10.3126/ajms.v6i1.10018   Asian Journal of Medical Sciences Vol.6(1) 2015 122-123
