Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2023The c.401C>G (p.S134W) alteration is located in exon 4 (coding exon 4) of the OLFM2 gene. This alteration results from a C to G substitution at nucleotide position 401, causing the serine (S) at amino acid position 134 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
