Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 17, 2024The c.2474C>A (p.T825N) alteration is located in exon 21 (coding exon 21) of the OVCH1 gene. This alteration results from a C to A substitution at nucleotide position 2474, causing the threonine (T) at amino acid position 825 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
