Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2022The c.688G>A (p.A230T) alteration is located in exon 3 (coding exon 3) of the C1QTNF7 gene. This alteration results from a G to A substitution at nucleotide position 688, causing the alanine (A) at amino acid position 230 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
