Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2023The c.3293G>C (p.R1098T) alteration is located in exon 27 (coding exon 27) of the OVCH1 gene. This alteration results from a G to C substitution at nucleotide position 3293, causing the arginine (R) at amino acid position 1098 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
