Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.914C>T (p.P305L) alteration is located in exon 6 (coding exon 6) of the OLFM2 gene. This alteration results from a C to T substitution at nucleotide position 914, causing the proline (P) at amino acid position 305 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
