[MOH SCREENING FOR TBCD IN COCHIN JEWS: COLLABORATION BETWEEN MEDICAL, RESEARCH AND COMMUNITY MEMBERS IN ACHIEVING PUBLIC HEALTH GOALS].

PEBAT (Progressive Encephalopathy, Early-Onset, with Brain Atrophy and Thin Corpus Callosum) is a rare disease characterized by a significant and progressive, neurological deficit. The disease has autosomal recessive etiology and is caused by bi-allelic variants in the gene TBCD (Tubulin-Specific Chaperone D). In 2017 the disease was diagnosed in two sisters from Jewish Cochin ethnicity (originating in Karela in south India) in Israel. Genetic testing for the girls revealed the homozygous TBCD variant c.1423G>A (p.Ala475Thr). This variant was reported simultaneously in another unrelated patient of Cochin origin.
