Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 18, 2021The c.278A>G (p.K93R) alteration is located in exon 1 (coding exon 1) of the C1GALT1C1L gene. This alteration results from a A to G substitution at nucleotide position 278, causing the lysine (K) at amino acid position 93 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
