Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.1270C>T (p.R424W) alteration is located in exon 4 (coding exon 4) of the SYNPO2L gene. This alteration results from a C to T substitution at nucleotide position 1270, causing the arginine (R) at amino acid position 424 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
