Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.200G>A (p.R67H) alteration is located in exon 2 (coding exon 2) of the OLFM3 gene. This alteration results from a G to A substitution at nucleotide position 200, causing the arginine (R) at amino acid position 67 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
