Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 09, 2022 | The c.1427T>C (p.I476T) alteration is located in exon 14 (coding exon 13) of the CCDC38 gene. This alteration results from a T to C substitution at nucleotide position 1427, causing the isoleucine (I) at amino acid position 476 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
