not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2024The c.2559G>C (p.K853N) alteration is located in exon 22 (coding exon 22) of the OVCH1 gene. This alteration results from a G to C substitution at nucleotide position 2559, causing the lysine (K) at amino acid position 853 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
