Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 26, 2024The c.62C>T (p.P21L) alteration is located in exon 1 (coding exon 1) of the OLFM3 gene. This alteration results from a C to T substitution at nucleotide position 62, causing the proline (P) at amino acid position 21 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
