Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2024The c.1088C>T (p.P363L) alteration is located in exon 11 (coding exon 9) of the SPATA21 gene. This alteration results from a C to T substitution at nucleotide position 1088, causing the proline (P) at amino acid position 363 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
