Genes affected
SCGB1A1 (HGNC:12523): (secretoglobin family 1A member 1) This gene encodes a member of the secretoglobin family of small secreted proteins. The encoded protein has been implicated in numerous functions including anti-inflammation, inhibition of phospholipase A2 and the sequestering of hydrophobic ligands. Defects in this gene are associated with a susceptibility to asthma. [provided by RefSeq, May 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.56C>T (p.A19V) alteration is located in exon 2 (coding exon 2) of the SCGB1A1 gene. This alteration results from a C to T substitution at nucleotide position 56, causing the alanine (A) at amino acid position 19 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
