Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 26, 2024The c.1192A>G (p.K398E) alteration is located in exon 8 (coding exon 7) of the OSGEPL1 gene. This alteration results from a A to G substitution at nucleotide position 1192, causing the lysine (K) at amino acid position 398 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
