Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 16, 2024The c.2180G>C (p.R727P) alteration is located in exon 20 (coding exon 19) of the ASCC2 gene. This alteration results from a G to C substitution at nucleotide position 2180, causing the arginine (R) at amino acid position 727 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
