Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2021The c.422G>A (p.G141E) alteration is located in exon 3 (coding exon 3) of the C1QTNF7 gene. This alteration results from a G to A substitution at nucleotide position 422, causing the glycine (G) at amino acid position 141 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
