Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.970T>G (p.S324A) alteration is located in exon 6 (coding exon 5) of the OSGEPL1 gene. This alteration results from a T to G substitution at nucleotide position 970, causing the serine (S) at amino acid position 324 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
