Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.223G>A (p.E75K) alteration is located in exon 3 (coding exon 2) of the C1QTNF9 gene. This alteration results from a G to A substitution at nucleotide position 223, causing the glutamic acid (E) at amino acid position 75 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
