Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.1124C>A (p.T375N) alteration is located in exon 2 (coding exon 1) of the AFTPH gene. This alteration results from a C to A substitution at nucleotide position 1124, causing the threonine (T) at amino acid position 375 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
