Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2024The c.860C>T (p.T287I) alteration is located in exon 9 (coding exon 6) of the PIP5K1B gene. This alteration results from a C to T substitution at nucleotide position 860, causing the threonine (T) at amino acid position 287 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
