Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2023The c.1210G>T (p.A404S) alteration is located in exon 14 (coding exon 13) of the OC90 gene. This alteration results from a G to T substitution at nucleotide position 1210, causing the alanine (A) at amino acid position 404 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
