35902954 - Biallelic NBAS variants identifed in three HLH patients who harbored no pathogenic variants in any of the known HLH genes. Functionally, impaired NK-cell cytotoxicity and degranulation were revealed in both NBAS biallelic variant patients and in an NBAS-defcient NK-cell line. Knockdown of NBAS in an NK-cell line (IMC-1) using short hairpin RNA (shRNA) resulted in loss of lytic granule polarization and a decreased number of cytotoxic vesicles near the Golgi apparatus.

PMID 31761904: a cohort of >100 individuals with bi-allelic NBAS variants. Based on the localization of missense variants and in-frame deletions, three clinical subgroups defined that differ significantly regarding main clinical features and are directly related to the affected region of the NBAS protein: β-propeller (combined phenotype), Sec39 (infantile liver failure syndrome type 2/ILFS2), and C-terminal (short stature, optic atrophy, and Pelger-Huët anomaly/SOPH).
