Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.161G>A (p.C54Y) alteration is located in exon 3 (coding exon 3) of the SPINK4 gene. This alteration results from a G to A substitution at nucleotide position 161, causing the cysteine (C) at amino acid position 54 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
