Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.746G>A (p.G249E) alteration is located in exon 6 (coding exon 6) of the OLFM2 gene. This alteration results from a G to A substitution at nucleotide position 746, causing the glycine (G) at amino acid position 249 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
