Stuttering is a neuro-developmental speech impairment characterized by uncontrolled utterances (interjections) and core behaviors (blocks, repetitions, and prolongations), and is caused by the failure of speech sensorimotors. Due to its complex nature, stuttering detection (SD) is a difficult task. If detected at an early stage, it could facilitate speech therapists to observe and rectify the speech patterns of persons who stutter (PWS).

We investigated HCC that segregates in three inbred families (LUCC03, LUCC16, and LUCC24). Ophthalmological examinations revealed cataracts with variability related to the age of onset segregating in a recessive manner in these families.

Purpose: Cone rod dystrophy (CRD) is a group of inherited retinopathies characterized by the loss of cone and rod photoreceptor cells, which results in poor vision. This study aims to clinically and genetically characterize the segregating CRD phenotype in two large, consanguineous Pakistani families.
Methods: Funduscopy, optical coherence tomography (OCT), electroretinography (ERG), color vision, and visual acuity assessments were performed to evaluate the retinal structure and function of the affected individuals.
Purpose: Primary congenital glaucoma (PCG) is a clinically and genetically heterogeneous disease. The present study was undertaken to find the genetic causes of PCG segregating in 36 large consanguineous Pakistani families.
Methods: Ophthalmic examination including fundoscopy, or slit-lamp microscopy was performed to clinically characterize the PCG phenotype.
Aim: To find the mutations associated with primary congenital glaucoma (PCG) in Pakistani consanguineous pedigrees.
Methods: After getting informed consent, 11 consanguineous pedigrees belonging to different ethnic groups were enrolled. Detailed medical history was recorded and pedigrees were drawn.
Purpose: This study aimed to investigate the role of CYP1B1 mutations in primary congenital glaucoma (PCG) in Pakistani patients.
Methods: After consent was received, 20 families with at least more than one member affected with primary congenital glaucoma were enrolled in the study. The disease was confirmed with standard ophthalmological investigations.
Glaucoma is one of the major causes of blindness worldwide with characteristic optic disc changes and elevated intraocular pressure. It is subcategorized into Primary Open Angle Glaucoma (POAG) and Juvenile Open Angle Glaucoma (JOAG) depending upon age of the disease onset. Myocilin (MYOC) is the frequently mutated gene in familial cases of glaucoma.
