Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2023The c.1738G>T (p.A580S) alteration is located in exon 8 (coding exon 8) of the OLFML2B gene. This alteration results from a G to T substitution at nucleotide position 1738, causing the alanine (A) at amino acid position 580 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
