Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 11, 2023The c.55G>A (p.G19S) alteration is located in exon 1 (coding exon 1) of the PARD3B gene. This alteration results from a G to A substitution at nucleotide position 55, causing the glycine (G) at amino acid position 19 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
