Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.677T>G (p.I226S) alteration is located in exon 5 (coding exon 4) of the CTDSPL2 gene. This alteration results from a T to G substitution at nucleotide position 677, causing the isoleucine (I) at amino acid position 226 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
