Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2022The c.469A>G (p.K157E) alteration is located in exon 2 (coding exon 2) of the CAAP1 gene. This alteration results from a A to G substitution at nucleotide position 469, causing the lysine (K) at amino acid position 157 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
