Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.982G>A (p.A328T) alteration is located in exon 6 (coding exon 5) of the OSGEPL1 gene. This alteration results from a G to A substitution at nucleotide position 982, causing the alanine (A) at amino acid position 328 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
