Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 22, 2022The c.236G>A (p.R79Q) alteration is located in exon 3 (coding exon 3) of the LMNTD2 gene. This alteration results from a G to A substitution at nucleotide position 236, causing the arginine (R) at amino acid position 79 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
