Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2023The c.783G>T (p.Q261H) alteration is located in exon 3 (coding exon 1) of the PHOSPHO1 gene. This alteration results from a G to T substitution at nucleotide position 783, causing the glutamine (Q) at amino acid position 261 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
