Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 16, 2024The c.1255G>C (p.A419P) alteration is located in exon 1 (coding exon 1) of the SBSN gene. This alteration results from a G to C substitution at nucleotide position 1255, causing the alanine (A) at amino acid position 419 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
