Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.353C>T (p.A118V) alteration is located in exon 4 (coding exon 2) of the C1QTNF8 gene. This alteration results from a C to T substitution at nucleotide position 353, causing the alanine (A) at amino acid position 118 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
