Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.1948C>A (p.Q650K) alteration is located in exon 13 (coding exon 12) of the CCDC57 gene. This alteration results from a C to A substitution at nucleotide position 1948, causing the glutamine (Q) at amino acid position 650 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
