A patient with a unique form of large granular lymphocytosis and multiple cranial neuritis is reported. The patient presented with facial weakness, diplopia and dysarthria. An increase in large granular lymphocytes (LGLs) was seen in blood (1.8 x 10(9)/l), CSF (237/microliters) and bone marrow (20% in a normocellular bone marrow). The phenotype of the LGLs in CSF, blood and bone marrow was CD2+ CD3+ CD4+ CD8- CD16- CD56- and CD57-. The unique features of this case include the CD4+ phenotype, the relative abundance of CSF LGL and the clinical presentation.

Phosphatidylinositol Glycan Anchor Biosynthesis class H (PIGH) is an essential player in the glycosylphosphatidylinositol (GPI) synthesis, an anchor for numerous cell membrane-bound proteins. PIGH deficiency is a newly described and rare disorder associated with developmental delay, seizures and behavioral difficulties. Herein, we report three new unrelated families with two different bi-allelic PIGH variants, including one new variant p.(Arg163Trp) which seems associated with a more severe phenotype. The common clinical features in all affected individuals are developmental delay/intellectual disability and hypotonia. Variable clinical features include seizures, autism spectrum disorder, apraxia, severe language delay, dysarthria, feeding difficulties, facial dysmorphisms, microcephaly, strabismus, and musculoskeletal anomalies. The two siblings homozygous for the p.(Arg163Trp) variant have severe symptoms including profound psychomotor retardation, intractable seizures, multiple bone fractures, scoliosis, loss of independent ambulation, and delayed myelination on brain MRI. Serum iron levels were significantly elevated in one individual. All tested individuals with PIGH deficiency had normal alkaline phosphatase and CD16, a GPI-anchored protein (GPI-AP), was found to be decreased by 60% on granulocytes from one individual. This study expands the PIGH deficiency phenotype range toward the severe end of the spectrum with the identification of a novel pathogenic variant.
