Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2021The c.922G>A (p.G308S) 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 922, causing the glycine (G) at amino acid position 308 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
