Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2024The c.4006G>A (p.A1336T) alteration is located in exon 20 (coding exon 19) of the PIK3R4 gene. This alteration results from a G to A substitution at nucleotide position 4006, causing the alanine (A) at amino acid position 1336 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
