Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2023The c.1249A>G (p.I417V) alteration is located in exon 6 (coding exon 6) of the OLFM2 gene. This alteration results from a A to G substitution at nucleotide position 1249, causing the isoleucine (I) at amino acid position 417 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
