Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.419A>T (p.Y140F) alteration is located in exon 2 (coding exon 1) of the KPRP gene. This alteration results from a A to T substitution at nucleotide position 419, causing the tyrosine (Y) at amino acid position 140 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
