Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2023The c.743A>G (p.Y248C) alteration is located in exon 7 (coding exon 6) of the SFTPD gene. This alteration results from a A to G substitution at nucleotide position 743, causing the tyrosine (Y) at amino acid position 248 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
