Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.219G>A (p.M73I) alteration is located in exon 1 (coding exon 1) of the CCDC27 gene. This alteration results from a G to A substitution at nucleotide position 219, causing the methionine (M) at amino acid position 73 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
