Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2022The c.488T>C (p.V163A) alteration is located in exon 4 (coding exon 2) of the C1QTNF8 gene. This alteration results from a T to C substitution at nucleotide position 488, causing the valine (V) at amino acid position 163 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
