Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2024The c.676C>T (p.R226C) alteration is located in exon 3 (coding exon 3) of the C1QTNF6 gene. This alteration results from a C to T substitution at nucleotide position 676, causing the arginine (R) at amino acid position 226 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
