Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.4G>T (p.V2L) alteration is located in exon 1 (coding exon 1) of the SPATA33 gene. This alteration results from a G to T substitution at nucleotide position 4, causing the valine (V) at amino acid position 2 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
