Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2023The c.542T>G (p.I181S) alteration is located in exon 2 (coding exon 1) of the AFTPH gene. This alteration results from a T to G substitution at nucleotide position 542, causing the isoleucine (I) at amino acid position 181 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
