Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.724G>T (p.G242C) 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 724, causing the glycine (G) at amino acid position 242 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
