Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.2237A>T (p.Q746L) alteration is located in exon 19 (coding exon 19) of the CEP89 gene. This alteration results from a A to T substitution at nucleotide position 2237, causing the glutamine (Q) at amino acid position 746 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
