ﷺ
خدا کا آخری پیغام لے کر آنے والے آپؐ
جہاں میں رونقِ اسلام لے کر آنے والے آپؐ
جہاں پر نور اور ظلمت میں کچھ تفریق ہی نہ تھی
وہاں تفریقِ صبح و شام لے کر آنے والے آپؐ
منات و لات و عزّی کا تھا صدیوں سے وہاں قبضہ
خدا کے گھر خدا کا نام لے کر آنے والے آپؐ
بہارِ جاوداں دنیا کے ویرانوں سے پھوٹی ہے
جہانِ خار میں گلفام لے کر آنے والے آپؐ
سحابِ رحمتِ کُل ؛ کھل کے برسا دشت و صحرا پر
خدا کی رحمتیں ہر گام لے کر آنے والے آپؐ
کلامِ گُل فشاں سے باغِ اقرا میں بہار آئی
خزانہ لوح کا بے دام لے کر آنے والے آپؐ
سرِ کوثر ، لبِ عرفانؔ بھی سیراب ہو اے کاش
مئے توحید کا بھی جام لے کر آنے والے آپؐ
The aim of this analysis was to ascertain the degree to which the Head of the Integrated Business Services Office's Leadership Style affects the efficacy of the Integrated Business Services Office's management. In data analysis, a descriptive study of one variable was performed to determine the percentage trend of each test variable; second, the commodity moment correlation formula was used to analyze variable relationships; and third, a basic equation model was used to analyze the impact relationship between the independent and dependent variables. The data for this study were processed using a micro statistical program with the assistance of a computer program. The data analysis and interpretation of the study's hypotheses indicate that there is a significant relationship and influence between the variable leadership style of the Integrated Business Services Office's Head and the effectiveness of the Integrated Business Services Office's management, at the 5% significance level or P = 0, 05, respectively.
Deafness is one of the most common human genetic disorders and exhibits high genetic heterogeneity. The prevalence of hearing loss is very high; about 5% people suffer from hearing loss worldwide. The estimated incidence of hearing loss is approximately 7 to 8 individuals per 1000 in Pakistan. Genetic hearing loss is known to have high inter- and intrafamilial heterogeneity. There are more than 64 known genes with thousands of mutations for non-syndromic recessively inherited hearing loss. Some genes involved in moderate to severe hearing loss have been identified in Pakistani population. However, many individuals with this phenotype do not currently have a genetic diagnosis which emphasizes the need for continued research. Participants from seventeen families were included in the current study and most of affected individuals in these families had moderate to severe degree of hearing loss. The criteria of ascertaining a family included multiple affected individuals, consanguinity of parents, a recessive mode of inheritance and less than profound degree of hearing loss. Homozygosity mapping and targeted custom capture were carried out for known deafness genes. This was followed by exome sequencing. Known as well as novel variants were identified in the deafness genes. Variants in SLC26A4 were the most common in this cohort. Pathogenic variants in GJB2, TMC1, MYO15A, CLDN14, TMPRSS3 and SLC52A3 were also found to segregate in the participating families. In a family PKSN3, exome data revealed a variant in a novel hearing loss gene DFNBX2. It was a frameshift mutation which was found segregating with moderate to severe degree of hearing loss. The variant was predicted to introduce a premature stop codon which may lead to nonsense mediated decay of the mRNA. DFNBX2 was localized to the tips and at the base of the sterocilia in the cochlea as determined by immunohistochemistry in mice. DFNBX2 also co-localized with tubulin in the inner ear of mice which suggests the role of this protein in contributing to the cytoskeleton of these cells. SNP genotyping was performed for six families, HLAI-22, HLAM01, HLGM02, HLAM03, HLAM12 and HLAM13 for which no pathogenic variant was identified in the exome data. For family HLAI-22, a linkage interval was mapped on chromosome 12. A noncoding iv variant in 5′ UTR of a gene DFNBX3 was identified within the linkage interval. DFNBX3 has a well-established role in the development of the inner ear, though variants of this gene have not been described in hearing loss. It is expressed in the inner ear at embryonic stages and the expression is continued after the development of the inner ear structures. The variant was predicted to disrupt the two regulatory RNA motifs, terminal oligopyrimidine tract (TOP) and the internal ribosome entry sites of the gene. Therefore, the variant can affect posttranslational modifications and may cause unregulated translation. Intra-familial heterogeneity was observed in three families HLAM08, HLAM01 and HLAM12 which made the identification of causative variant difficult. In family HLAM08 known variant in TMPRSS3 was found causative for two of three affected individuals hearing loss. In a few affected individuals of families HLAM01 and HLAM12, founder mutations of SLC26A4 were identified which could account for their hearing loss. However, no single region of shared homozygosity was identified for remaining four affected individuals of family HLAM01 and six affected individual of family HLAM12 which indicates further genetic heterogeneity in these families. In families HLGM02, HLAM03 and HLAM13, single linkage intervals were mapped on chromosomes 1, 19 and 9 respectively by SNP genotyping. However, no variants were identified after sequencing the uncovered exons located in the respective linkage intervals. These families in which the current study failed to yield the pathogenic variants can be investigated further using whole genome sequencing on several affected and unaffected individuals. This will be helpful to identify pathogenic variants and will broaden the understanding of moderate to severe hearing loss.
