Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 26, 2024The c.213C>A (p.H71Q) alteration is located in exon 3 (coding exon 3) of the ALG1L2 gene. This alteration results from a C to A substitution at nucleotide position 213, causing the histidine (H) at amino acid position 71 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
