Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2022The c.1609G>A (p.E537K) alteration is located in exon 12 (coding exon 12) of the COLGALT2 gene. This alteration results from a G to A substitution at nucleotide position 1609, causing the glutamic acid (E) at amino acid position 537 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
