Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 01, 2022The c.697A>G (p.M233V) 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 697, causing the methionine (M) at amino acid position 233 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
