Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2023The c.671T>G (p.I224S) alteration is located in exon 9 (coding exon 7) of the CC2D2B gene. This alteration results from a T to G substitution at nucleotide position 671, causing the isoleucine (I) at amino acid position 224 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
