Added comment: PMID: 39648562 (Toms et al., 2024) reports a patient with bilateral sensorineural hearing loss, heterozygous for a de novo variant in NTN1: NM_004822.3:c.1483T>A p.(Tyr495Asn). Sequencing method: WGS.The patient (Female, 30 years old, White British) also had chorioretinal coloboma and microphthalmia, and right hand polydactyly. The C-terminus variant is not found in gnomAD v4.1.0; in silico prediction tools: Revel score = 0.5 (Uncertain), AlphaMissense score = 0.806 (Deleterious Supporting).

In PMID: 39648562, morpholino knockdown of ntn1a in zebrafish (86% gene similarity to human ortholog) had ocular coloboma and sensory hair cell defects. At 5 dpf, hair cells of the lateral line neuromasts were found have abnormal morphology. There was also a significant reduction in the overall number of sensory hair cells present.
