Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.433A>G (p.I145V) alteration is located in exon 4 (coding exon 4) of the AMN1 gene. This alteration results from a A to G substitution at nucleotide position 433, causing the isoleucine (I) at amino acid position 145 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
