The c.198C>A (p.D66E) alteration is located in exon 3 (coding exon 2) of the LEMD1 gene. This alteration results from a C to A substitution at nucleotide position 198, causing the aspartic acid (D) at amino acid position 66 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
