Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.494T>C (p.M165T) alteration is located in exon 2 (coding exon 2) of the MBLAC2 gene. This alteration results from a T to C substitution at nucleotide position 494, causing the methionine (M) at amino acid position 165 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
