Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 21, 2022The c.115G>A (p.G39S) alteration is located in exon 2 (coding exon 2) of the UNC93A gene. This alteration results from a G to A substitution at nucleotide position 115, causing the glycine (G) at amino acid position 39 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
