Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2022The c.26T>C (p.L9P) alteration is located in exon 1 (coding exon 1) of the UNC93A gene. This alteration results from a T to C substitution at nucleotide position 26, causing the leucine (L) at amino acid position 9 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
