Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 09, 2022The c.5773A>C (p.N1925H) 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 5773, causing the asparagine (N) at amino acid position 1925 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
