Several neurological disorders, neurodevelopmental disorders, and neurodegenerative disorders have a genetic element with various clinical presentations ranging from mild to severe presentation. Neurological disorders are rare multifactorial disorders characterized by dysfunction and degeneration of synapses, neurons, and glial cells which are essential for movement, coordination, muscle strength, sensation, and cognition. The cerebellum might be involved at any time, either during development and maturation or later in life. Herein, we describe a spectrum of NDDs and NDs in seven patients from six Egyptian families. The core clinical and radiological features of our patients included dysmorphic features, neurodevelopmental delay or regression, gait abnormalities, skeletal deformities, visual impairment, seizures, and cerebellar atrophy. Previously unreported clinical phenotypic findings were recorded. Whole-exome sequencing (WES) was performed followed by an in silico analysis of the detected genetic variants' effect on the protein structure. Three novel variants were identified in three genes MFSD8, AGTPBP1, and APTX, and other previously reported three variants have been detected in "TPP1, AGTPBP1, and PCDHGC4" genes. In this cohort, we described the detailed unique phenotypic characteristics given the identified genetic profile in patients with neurological "neurodevelopmental disorders and neurodegenerative disorders" disorders associated with cerebellar atrophy, hence expanding the mutational spectrum of such disorders.
