Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.226G>A (p.G76R) alteration is located in exon 2 (coding exon 2) of the SPATA25 gene. This alteration results from a G to A substitution at nucleotide position 226, causing the glycine (G) at amino acid position 76 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
