Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2022The c.740G>T (p.G247V) alteration is located in exon 6 (coding exon 6) of the CAAP1 gene. This alteration results from a G to T substitution at nucleotide position 740, causing the glycine (G) at amino acid position 247 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
