Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.725C>T (p.T242M) alteration is located in exon 4 (coding exon 3) of the C1QTNF9 gene. This alteration results from a C to T substitution at nucleotide position 725, causing the threonine (T) at amino acid position 242 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
