Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.124G>A (p.G42S) alteration is located in exon 3 (coding exon 1) of the PHOSPHO1 gene. This alteration results from a G to A substitution at nucleotide position 124, causing the glycine (G) at amino acid position 42 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
