Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.14G>C (p.R5P) alteration is located in exon 1 (coding exon 1) of the SPATA20 gene. This alteration results from a G to C substitution at nucleotide position 14, causing the arginine (R) at amino acid position 5 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
