Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2024The c.1073G>A (p.R358Q) alteration is located in exon 11 (coding exon 9) of the SPATA21 gene. This alteration results from a G to A substitution at nucleotide position 1073, causing the arginine (R) at amino acid position 358 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
