Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.229G>C (p.D77H) alteration is located in exon 4 (coding exon 4) of the SPINK4 gene. This alteration results from a G to C substitution at nucleotide position 229, causing the aspartic acid (D) at amino acid position 77 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
