Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 07, 2023The c.922G>A (p.A308T) alteration is located in exon 4 (coding exon 4) of the GPR157 gene. This alteration results from a G to A substitution at nucleotide position 922, causing the alanine (A) at amino acid position 308 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
