Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.2599G>A (p.V867I) alteration is located in exon 4 (coding exon 4) of the SYNPO2L gene. This alteration results from a G to A substitution at nucleotide position 2599, causing the valine (V) at amino acid position 867 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
