Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 27, 2023The c.40C>T (p.R14W) alteration is located in exon 2 (coding exon 2) of the SYNPR gene. This alteration results from a C to T substitution at nucleotide position 40, causing the arginine (R) at amino acid position 14 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
