Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 12, 2024The c.17G>A (p.C6Y) 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 17, causing the cysteine (C) at amino acid position 6 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
