Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.2165C>A (p.T722N) alteration is located in exon 8 (coding exon 8) of the OLFML2B gene. This alteration results from a C to A substitution at nucleotide position 2165, causing the threonine (T) at amino acid position 722 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
