Genes affected

ATOH1 (HGNC:797): (atonal bHLH transcription factor 1) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in neuron differentiation; positive regulation of neuron differentiation; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including generation of neurons; inner ear morphogenesis; and positive regulation of inner ear auditory receptor cell differentiation. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.254C>T (p.P85L) alteration is located in exon 1 (coding exon 1) of the ATOH1 gene. This alteration results from a C to T substitution at nucleotide position 254, causing the proline (P) at amino acid position 85 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
