Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 23, 2023The c.181G>A (p.A61T) alteration is located in exon 1 (coding exon 1) of the CRAMP1 gene. This alteration results from a G to A substitution at nucleotide position 181, causing the alanine (A) at amino acid position 61 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
