Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.130C>T (p.L44F) alteration is located in exon 1 (coding exon 1) of the C2orf54 gene. This alteration results from a C to T substitution at nucleotide position 130, causing the leucine (L) at amino acid position 44 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
