Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 05, 2024The c.544T>G (p.C182G) alteration is located in exon 4 (coding exon 4) of the UNC93A gene. This alteration results from a T to G substitution at nucleotide position 544, causing the cysteine (C) at amino acid position 182 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
