Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.829A>G (p.K277E) alteration is located in exon 2 (coding exon 1) of the AFTPH gene. This alteration results from a A to G substitution at nucleotide position 829, causing the lysine (K) at amino acid position 277 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
