Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2022The c.1079G>C (p.G360A) alteration is located in exon 13 (coding exon 12) of the OC90 gene. This alteration results from a G to C substitution at nucleotide position 1079, causing the glycine (G) at amino acid position 360 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
