Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.134C>T (p.A45V) alteration is located in exon 3 (coding exon 3) of the PALMD gene. This alteration results from a C to T substitution at nucleotide position 134, causing the alanine (A) at amino acid position 45 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
