Genes affected
OTX1 (HGNC:8521): (orthodenticle homeobox 1) This gene encodes a member of the bicoid sub-family of homeodomain-containing transcription factors. The encoded protein acts as a transcription factor and may play a role in brain and sensory organ development. A similar protein in mouse is required for proper brain and sensory organ development and can cause epilepsy. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.233C>T (p.P78L) alteration is located in exon 4 (coding exon 2) of the OTX1 gene. This alteration results from a C to T substitution at nucleotide position 233, causing the proline (P) at amino acid position 78 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
