Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.76C>T (p.R26W) alteration is located in exon 2 (coding exon 2) of the C1QTNF7 gene. This alteration results from a C to T substitution at nucleotide position 76, causing the arginine (R) at amino acid position 26 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
