Function
Functional validation in single- and double-heterozygous mouse models carrying these variants recapitulated TOF-like phenotypes and impaired normal cilia structure and function, particularly disrupting Hedgehog signaling in cardiomyocytes, and down-regulating key transcription factors Gata4 and Nkx2-5(PMID: 41071877).
Model organism evidence
Axonemal Central Pair Apparatus Protein (HYDIN) is a ciliary protein previously linked to congenital cardiomyopathy.
LZTFL1 participates in immune synapse formation, ciliogenesis, and the localization of ciliary proteins, and knockout of LZTFL1 induces abnormal distribution of heterotetrameric adaptor protein complex-1 (AP-1) in the Lztfl1-knockout mouse photoreceptor cells, suggesting that LZTFL1 is involved i
