Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 12, 2024The c.958C>T (p.P320S) alteration is located in exon 12 (coding exon 11) of the OC90 gene. This alteration results from a C to T substitution at nucleotide position 958, causing the proline (P) at amino acid position 320 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
