The c.406G>A (p.G136S) alteration is located in exon 4 (coding exon 4) of the TLCD1 gene. This alteration results from a G to A substitution at nucleotide position 406, causing the glycine (G) at amino acid position 136 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
