Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 16, 2024The c.517C>T (p.L173F) alteration is located in exon 5 (coding exon 5) of the CCDC138 gene. This alteration results from a C to T substitution at nucleotide position 517, causing the leucine (L) at amino acid position 173 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
