Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 11, 2023The c.100C>T (p.H34Y) alteration is located in exon 2 (coding exon 2) of the SPATA33 gene. This alteration results from a C to T substitution at nucleotide position 100, causing the histidine (H) at amino acid position 34 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
