not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 20, 2023The c.992G>A (p.R331Q) alteration is located in exon 1 (coding exon 1) of the ITPRIPL1 gene. This alteration results from a G to A substitution at nucleotide position 992, causing the arginine (R) at amino acid position 331 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
