Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.668T>C (p.M223T) alteration is located in exon 7 (coding exon 7) of the WDR75 gene. This alteration results from a T to C substitution at nucleotide position 668, causing the methionine (M) at amino acid position 223 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
