Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2022The c.551G>A (p.R184H) alteration is located in exon 3 (coding exon 3) of the WBSCR28 gene. This alteration results from a G to A substitution at nucleotide position 551, causing the arginine (R) at amino acid position 184 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
