Collection Method:clinical testing

The c.334G>A (p.G112S) alteration is located in exon 4 (coding exon 3) of the SFTPD gene. This alteration results from a G to A substitution at nucleotide position 334, causing the glycine (G) at amino acid position 112 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
