Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2023The c.146C>G (p.P49R) alteration is located in exon 1 (coding exon 1) of the SLAIN2 gene. This alteration results from a C to G substitution at nucleotide position 146, causing the proline (P) at amino acid position 49 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
