Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2021The c.749G>A (p.R250H) alteration is located in exon 12 (coding exon 12) of the CLEC17A gene. This alteration results from a G to A substitution at nucleotide position 749, causing the arginine (R) at amino acid position 250 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
