Web8 dec. 2024 · How is Tay Sachs disease inherited from parents? Autosomal recessive inheritance means that a person receives a nonworking copy of the HEXA gene from both parents. The parents have one working copy of the gene and one nonworking copy; they are carriers for Tay-Sachs disease. Carriers do not develop symptoms of the disorder. WebTay–Sachs disease (TSD) would be one such candidate, however very little is known about the presymptomatic stage of TSD. To better understand the effects of TSD on brain development, we evaluated the transcriptomes of human fetal brain samples with biallelic pathogenic variants in HEXA .
