INTRODUCTION

Multiple congenital anomalies-hypotonia-seizures syndrome 1 (MCAHS1) associated with mutations ingene, is an autosomal recessive disease featured as epilepsy, stunting, hypotonica, and various congenital disorders. This was initially described in 2011[1]. Mutation in thegene involved in GPI-anchor pathway have been identified cause varied neurological abnormalities[1-4].The authors report on a 16 years old girl who was presented with epilepsy, developmental delay and cerebellar atrophy. She harbors a compound heterozygous variant in thegene, include a nonsense splice site mutation (c.2557A>C) which was inherited from her mother, and a novel site mutation (c.980del) which was inherited from her father.

CASE PRESENTATION

Chief complaints

A female, 16 years old, was presented with epilepsy, developmental delay and cerebellar atrophy.

History of present illness

Clinical examination documented the eyes were deep set with nystagmus, a small nose with nasalbridge (Figure 1).

The authors will keep on to follow the patient’s disease development. This diagnosis allowed permitted appropriate genetic counseling with related risk evaluation.

Personal and family history

The patient was the second child of the family (non-consanguineous), her mother was 33 years old. She was born at full term with normal birth parameters, the pregnancy was normal, there was no known teratogenic exposure.

The parents does not have a personal history of seizures, nor is there a family history seizures.

Physical examination

Weakness of muscles was noticed at age 2 years old. At 1 year of age, she developed clinical seizures. Her seizure types include twitching movements, starting episodes, cluster seizures, and spasms. At a year and a half, there was only partial response to anti-convulsive therapy. Subsequently, global developmental delay was noted by 2 years old of age, there was no speech, and she needed assistance with daily life activities.

Laboratory examinations

Whole exome sequencing (WES) was performed commercially at Berrygenomics on the patient and her parents. Sequencing was performed on Illumina Novaseq 6000 (Illumina, San Diego, United States), using the Nano WES Human Exome V1.0 (Berrygenomics, Beijing, China) kit with 200 bp paired-end read, according to the manufacturer’s instructions. Annotation of variants was performed using GATK (https://software.broadinstitute.org/gatk/), gnomAD (http://gnomad.broadinstitute.org/), 1000genomes (http://browser.1000genomes.org), SIFT (http://sift.jcvi.org), FATHMM (http://fathmm.biocompute.org.uk), MutationAssessor (http://mutationassessor.org), OMIM (http://www.omim.org), ClinVar (http://www.ncbi.nlm.nih.gov/clinvar), HGMD (http:// www.hgmd.org).

Imaging examinations

Neuropsychological testing demonstrated moderate intellectual disability. Brain imaging showed the progression of mild global cerebral volume loss and cerebellar atrophy. The parents could not provide the results of previous test, including brain magnetic resonance imaging, various metabolic tests.

FINAL DIAGNOSIS

Whole Exome sequencing was performed commercially at BerryGenomics on the patient and her parents. Compound heterozygous mutations ingene were found, maternally inherited c.2557A>C and paternally inherited c.980del. The mutations were validated by sanger sequencing in the patient and her parents (Figure 2).

The authors also examined several small insertion/deletion variants (Indels), but none of these had an apparent connection to the clinical phenotype.

TREATMENT

The present therapies for patients withgene associated illnesses are mainly supportive, which were aimed to reduce the development of epileptic seizures.

DISCUSSION

There are more than 20 genes that participated in GPI-anchor biosynthesis pathway.is responsible for supplement of phosphoethanolamine to the primary mannose in GPI[2]. Mutations in thegene involved in GPI biosynthesis, have been identified associated with MCAHS1[1,5,6]. The authors report a patient with epilepsy, global delay, cerebellar atrophy with amutation. The maternally inherited variant (c.2557A>C) has not been seen observed in the gnomAD and 1000genomes, which was called variants of unknown significance. The original mutation c.980del (paternally inherited) discovered in the prohand was estimated as “probably damaging”. The novel mutation changes the gene’s open reading frameshift, support the conclusion that the novel mutation detected in the patient cause major damage to the GPI-anchored protein, finally leading to the disorder.

Unlike previous reports[1,5,6], the patient did not have other visceral congenital anomalies of urinary, cardiac or gastrointestinal systems. Gastro-esophageal reflux, diaphragmatic hernia, brachycephaly, flat face, hypoplasia of distal parts of all fingers, open mouth, drooling have not been seen in the patient. Evaluation for mutations incausingassociated epilepsy or MCAHS1 should be considered in patients of all ethnicities with epilepsy. These phenotypic differences may be explained as allele specific effects.

Sequence analysis of exon 28 and 12 ofusing genomic DNA from the patient and her parents were performed by amplification of a 438 bp and 239 bp fragment containing the putative mutation identifiedexome sequencing. The sense primer sequence was 5’-TAAGTCAGTTTCATCACCGTTCTAT-3’ and the antisense primer sequence was 5’-ATTTCCTCTAATGACAAGCAACAC-3’ for exon 28. The sense primer sequence was 5’-TCTAGCAAATGACACTTTTAGAGA-3’, and the antisense primer sequence was 5’-TTCCTTACCACTGAGTTAAGAGG-3’ for exon 12.

The clinical severity of the disease seems to correlate with the predicted functional severity of the mutations seen in[6]. Depending upon the severity of mutations, major congenial anomalies may also be present. Other hypotheses of environmental and genetic modification need to be considered. It should also be noted here that for PIGN gene-associated with disability, some tissues are more sensitive than others during body development.

CONCLUSION

This case report expands the mutation spectrum found ingene, and strengthens the association betweenmutation and MCAHS1. Mutations ingene may be an underestimated cause of epilepsy. The authors recommend that, for patients with epilepsy or prenatal diagnosis of highly suspicious fetus, gene sequencing should be the preferred detection method.

我國(guó)城市人口逐年遞增，導(dǎo)致排放污水的數(shù)量越來(lái)越多。以往的城市排水系統(tǒng)，大部分都是將污水直接排放到道路的兩邊或周?chē)暮恿骼铮瑢?duì)城市環(huán)境造成了威脅，若依舊使用這種直接排放污水的方法，將會(huì)帶來(lái)嚴(yán)重的危害。因此，需確保城市排水的有效進(jìn)行，加大對(duì)排水系統(tǒng)的研究工作。在設(shè)計(jì)排水系統(tǒng)時(shí)，為防止因污水?dāng)?shù)量過(guò)于龐大導(dǎo)致污水不能順利地經(jīng)管道排出，從而對(duì)市民的生活造成影響，需要計(jì)算污水排放量。在排放污水時(shí)，還應(yīng)使用節(jié)能方式進(jìn)行排水，不斷加大污水的處理力度，同時(shí)也要提高對(duì)節(jié)能的重視程度。

發(fā)揚(yáng)風(fēng)格也不是隨意發(fā)揮，上文所提到的兩位翻譯家，魯迅和周作人，他們都認(rèn)為兒童文學(xué)翻譯作品的目標(biāo)讀者是兒童，因此應(yīng)該著重考慮兒童的閱讀習(xí)慣和心理。原文中一些晦澀難懂的詞匯應(yīng)該改成簡(jiǎn)單生動(dòng)的詞匯，所以在翻譯這些作品時(shí)，譯者要做二次創(chuàng)作。(夏丐尊，1983)[9]

從回歸系數(shù)t的數(shù)值來(lái)看，出口的對(duì)外直接投資彈性系數(shù)顯著.浙江省對(duì)外直接投資與出口之間存在著互補(bǔ)效應(yīng)，對(duì)外直接投資每增加1個(gè)百分點(diǎn)，浙江省的出口將會(huì)增加0.1個(gè)百分點(diǎn).一個(gè)可能的解釋是：一方面，對(duì)外直接投資的增加，使得浙江省與東道國(guó)的貿(mào)易聯(lián)系增加，從而有助于出口的增加；另一方面，浙江省對(duì)外直接投資一旦進(jìn)入生產(chǎn)階段，則促進(jìn)了中間品、原材料和技術(shù)的出口.同時(shí)根據(jù)式(5)還可以看出，距離與貿(mào)易量呈顯著的負(fù)相關(guān)性，表明地理位置會(huì)影響兩個(gè)國(guó)家或地區(qū)的貿(mào)易往來(lái)，而且是重要影響因素.此外，樣本國(guó)與浙江省是否擁有共同邊界或者同屬于一個(gè)貿(mào)易集團(tuán)，對(duì)出口、進(jìn)口貿(mào)易的影響比較小或者不明顯.
