Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.5786A>C (p.K1929T) alteration is located in exon 33 (coding exon 33) of the AHCTF1 gene. This alteration results from a A to C substitution at nucleotide position 5786, causing the lysine (K) at amino acid position 1929 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
