Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.331G>A (p.A111T) alteration is located in exon 2 (coding exon 2) of the PWWP2B gene. This alteration results from a G to A substitution at nucleotide position 331, causing the alanine (A) at amino acid position 111 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
