Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.922G>A (p.G308R) alteration is located in exon 4 (coding exon 3) of the C1QTNF9 gene. This alteration results from a G to A substitution at nucleotide position 922, causing the glycine (G) at amino acid position 308 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
