Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 20, 2024The c.169C>T (p.L57F) alteration is located in exon 2 (coding exon 2) of the UNC93A gene. This alteration results from a C to T substitution at nucleotide position 169, causing the leucine (L) at amino acid position 57 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
