Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 27, 2024The c.1031C>G (p.T344S) alteration is located in exon 11 (coding exon 9) of the SPATA21 gene. This alteration results from a C to G substitution at nucleotide position 1031, causing the threonine (T) at amino acid position 344 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
