not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2023The c.645C>A (p.H215Q) alteration is located in exon 8 (coding exon 8) of the APOOL gene. This alteration results from a C to A substitution at nucleotide position 645, causing the histidine (H) at amino acid position 215 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
