Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.430A>G (p.K144E) alteration is located in exon 4 (coding exon 4) of the OLFM3 gene. This alteration results from a A to G substitution at nucleotide position 430, causing the lysine (K) at amino acid position 144 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
