Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 11, 2023The c.80G>A (p.G27E) alteration is located in exon 2 (coding exon 2) of the SPINK4 gene. This alteration results from a G to A substitution at nucleotide position 80, causing the glycine (G) at amino acid position 27 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
