Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 24, 2024The c.1986G>T (p.K662N) alteration is located in exon 4 (coding exon 4) of the SYNPO2L gene. This alteration results from a G to T substitution at nucleotide position 1986, causing the lysine (K) at amino acid position 662 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
