Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 04, 2024The c.1912G>A (p.D638N) alteration is located in exon 8 (coding exon 8) of the OLFML2B gene. This alteration results from a G to A substitution at nucleotide position 1912, causing the aspartic acid (D) at amino acid position 638 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
