Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2024The c.718T>A (p.Y240N) alteration is located in exon 2 (coding exon 1) of the KPRP gene. This alteration results from a T to A substitution at nucleotide position 718, causing the tyrosine (Y) at amino acid position 240 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
