Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.301G>A (p.G101R) alteration is located in exon 3 (coding exon 3) of the UNC93A gene. This alteration results from a G to A substitution at nucleotide position 301, causing the glycine (G) at amino acid position 101 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
