Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.494C>G (p.S165C) alteration is located in exon 5 (coding exon 4) of the CTDSPL2 gene. This alteration results from a C to G substitution at nucleotide position 494, causing the serine (S) at amino acid position 165 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
