Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 07, 2022The c.227T>C (p.V76A) alteration is located in exon 3 (coding exon 2) of the ASUN gene. This alteration results from a T to C substitution at nucleotide position 227, causing the valine (V) at amino acid position 76 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
