Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1558G>A (p.V520I) alteration is located in exon 15 (coding exon 14) of the CCDC38 gene. This alteration results from a G to A substitution at nucleotide position 1558, causing the valine (V) at amino acid position 520 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
