Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2023The c.4G>A (p.G2S) alteration is located in exon 2 (coding exon 1) of the OSR1 gene. This alteration results from a G to A substitution at nucleotide position 4, causing the glycine (G) at amino acid position 2 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
