not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2024The c.321C>A (p.S107R) alteration is located in exon 2 (coding exon 1) of the OSR1 gene. This alteration results from a C to A substitution at nucleotide position 321, causing the serine (S) at amino acid position 107 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
