Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2024The c.1442C>G (p.T481S) alteration is located in exon 4 (coding exon 4) of the SYNPO2L gene. This alteration results from a C to G substitution at nucleotide position 1442, causing the threonine (T) at amino acid position 481 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
