Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1738G>A (p.A580T) alteration is located in exon 17 (coding exon 17) of the BBS1 gene. This alteration results from a G to A substitution at nucleotide position 1738, causing the alanine (A) at amino acid position 580 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
