Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 02, 2024The c.1798C>A (p.L600I) alteration is located in exon 12 (coding exon 11) of the CCDC57 gene. This alteration results from a C to A substitution at nucleotide position 1798, causing the leucine (L) at amino acid position 600 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
