Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2023The c.191G>C (p.R64P) alteration is located in exon 3 (coding exon 3) of the GLB1L3 gene. This alteration results from a G to C substitution at nucleotide position 191, causing the arginine (R) at amino acid position 64 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
