Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.473T>C (p.I158T) alteration is located in exon 4 (coding exon 4) of the CCDC43 gene. This alteration results from a T to C substitution at nucleotide position 473, causing the isoleucine (I) at amino acid position 158 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
