Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 19, 2024The c.237C>A (p.H79Q) alteration is located in exon 3 (coding exon 3) of the GLB1L3 gene. This alteration results from a C to A substitution at nucleotide position 237, causing the histidine (H) at amino acid position 79 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
