Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 25, 2022The c.721C>T (p.R241W) alteration is located in exon 6 (coding exon 6) of the OLFM2 gene. This alteration results from a C to T substitution at nucleotide position 721, causing the arginine (R) at amino acid position 241 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
