The c.4492G>C (p.D1498H) alteration is located in exon 30 (coding exon 29) of the LAMB4 gene. This alteration results from a G to C substitution at nucleotide position 4492, causing the aspartic acid (D) at amino acid position 1498 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
