Genes affected

AAGAB (HGNC:25662): (alpha and gamma adaptin binding protein) The protein encoded by this gene interacts with the gamma-adaptin and alpha-adaptin subunits of complexes involved in clathrin-coated vesicle trafficking. Mutations in this gene are associated with type I punctate palmoplantar keratoderma. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2012]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.13803971).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0000451 (65/1441982) while in subpopulation EAS AF= 0.00149 (59/39586). AF 95% confidence interval is 0.00119. There are 0 homozygotes in gnomad4_exome. There are 31 alleles in male gnomad4_exome subpopulation. Median coverage is 26. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 65 AD gene.

Ambry Genetics

May 18, 2023

The c.722T>C (p.M241T) alteration is located in exon 8 (coding exon 8) of the AAGAB gene. This alteration results from a T to C substitution at nucleotide position 722, causing the methionine (M) at amino acid position 241 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
