Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 03, 2023The c.640C>T (p.R214C) alteration is located in exon 2 (coding exon 2) of the MBLAC2 gene. This alteration results from a C to T substitution at nucleotide position 640, causing the arginine (R) at amino acid position 214 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
