Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 29, 2023The c.2585G>A (p.R862Q) alteration is located in exon 22 (coding exon 22) of the OVCH1 gene. This alteration results from a G to A substitution at nucleotide position 2585, causing the arginine (R) at amino acid position 862 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
